A buddy of mine is the son of a United Airlines mechanic who was fairly high up in the organization. When his dad passed United gave him a stack of blank wax tickets. His son could write the destination on them and fly for free. Near the end of the stack they were largely ornamental as he could just tell them where he wanted to go and they would print a proper ticket. But still, it was a rather classy way to honor his father.

How many apprentices did this guy managed to put through the pipeline before his career was over? It always shocks me how low this number tends to be for highly skilled craftsmen.

I work in a mid sized engineering organization, and the older engineers (and engineer-adjacent people like me) mentor the younger ones all the time.
One thing that can't be codified in procedures is what I call "situational awareness" for lack of a better term. I don't think you can learn how to work in a machine shop safely from a book. Or recognize when a complex design is heading towards being unworkable. In my organization, the older engineers have a sixth sense for projects that are going to be cancelled.
There's a reason why older drivers (up to a point of course) pay less for car insurance, yet the rules are the same for all of us.

Not to be negative about experts here, but of all industries, isn’t airline maintenance one of the most documented and standard procedure focused of them all? I would hope that someone maintaining a 777 doesn’t have to remember certain tricks or tips outside of what the manuals say, and when mistakes are found, they’d be noted, investigated and republished to all maintenance crews worldwide.

There is a famous story about how an F16 got grounded because an half inch metal pin was missing from the cockpit canopy. Nobody knew what the pin did or if it was even necessary but you can't fly a plan that 'missing a part'. After several days of being grounded they finally reached out to a guy who had retired 20 years ago who told them the pin was a part of a analogue sensor that had been replaced nearly 30 years ago. Only the pin remained as a vestigial organ since it was part of the airframe design.

It’s a great story, but I assure you there is a pretty high percentage of airplanes flying with missing parts and systems placarded as INOP in both military and civilian aviation.
buildsjets 35 minutes ago [-]
Before you can placard something as INOP, you must determine whether the manufacturer and certifying authority have included that part in the Minimum Equipment List or Dispatch Deviation List. Mechanics do both get to determine this at their own discretion. Hence the call to the manufacturer for clarification on the necessity of said pin.
To reiterate, you CANNOT fly an airplane with an undocumented missing part. If the part is documented in the logbook as removed, and it is acceptable to fly that way, then it is not missing.
I have been building and maintaining commercial aircraft for a living for 30 years. What is your experience?

I hope you're right :) You probably are too. But even with that, there is a reason it's a profession and not something we ask gig-workers to do, it takes expertise and skill like any other skilled work, even though all the literal actions one might take is technically written down somewhere. Even in such industries, experts would get "hunches" about what is wrong, and are able to quicker pinpoint issues, and similar things. Or "getting a bad feeling" before something is actually evidentially bad, which prevented human disaster more than once in history.
I think if you consider that the job couldn't be done by just anybody who can read and follow instructions, then it might not be as easy as just "follow what the manuals say" and in those cases expertise, knowledge and experience matters a great deal.

It's sad but at the same time there is a sort of optimization that tends to occur each time the magic trick is rediscovered.
Often it is not possible to separate the technique from the man. Things like riding a bike or flying a helicopter come to mind. A lot of what makes a master good cannot be written down anywhere. There isn't anything tangible to actually lose.
How would you write a document that describes to someone how to ride a bike or dig holes efficiently? You could explain the principles and general ideas, but the apprentice is going to need to get scraped up a bit before they actually learn anything that matters. The apprentice willing to suffer repeated failure is where most of the heavy lifting occurs. The master is mostly a backstop to keep the apprentice alive.
embedding-shape 6 hours ago [-]
> How would you write a document that describes to someone how to ride a bike or dig holes efficiently?
You don't. You put these people together for some years to work on stuff together, and a small percentage of this "intangible" feelings, knowledge and experiences you cannot write down somehow magically passes over to the other person.
Of course, the apprentice will still require their own repeated failures and uphill battle even getting close, but having someone who mastered the craft near you as you go through this, makes the whole process a hell of a lot faster.

Worse is that they who have the knowledge don't realise that others don't know what they know, it's completely automatic and ingrained to the owner.
There's nothing implied about tacit knowledge being knowledge that you don't know others don't have. For instance in chess mastery, one is fully aware that you simply see the board in a different way. It's not like you're aloof of your own 'advantage', but then in lessons you work to gradually, step by step, instill such in the student. Some of the most successful teachers are those who themselves learned the game a bit later than average, enabling them to draw more heavily on their own path.

I think they're touching on multiple things that typically happens between an apprentice and master, not just tacit knowledge.

You don't need to write it down to pass the knowledge down to an apprentice.
Your bicycle case is a great example. People don't learn to ride a bike from a book. They receive in-person instruction of exactly the type the comment you're responding to was writing about.
johnwalkr 3 hours ago [-]
One interesting thing about riding a bike is that to turn right, you must initially turn the handlebars to the left (called countersteering). This is subconscious, not explicitly taught and virtually everyone disbelieves this at first when told. But it's something that needs to "click" in order to ride a bike. It's the reason it is so hard to ride a carnival trick bike with a gear added to reverse the handlebar/steering relationship; you don't consciously know how to change your input. There's even some videos by bike youtubers that learn to ride a bike with reverse steering, including the subconscious countersteering part. When they switch back to a normal bike, it once again takes time to relearn.
To relate this back to the comment thread, people don't even always know the full extent of what they have learned.
That's why this is speaking about apprentice and not about lectures in an university.

Yes, this seems to happen a lot in small companies. It seems less inevitable in big ones but it still happens. You would think at a minimum AA would want to hire a journalist or similar simply to shadow him for a year, get him to dictate everything (so that he has to do as little extra effort as possible), and publish a sort-of manual from the accumulated wisdom.
The point of hiring someone specifically to do this is that he might simply want to keep on working, uninterrupted by apprentices or other demands, so the recorder must be a second person dedicated to knowledge maintenance.

Generally speaking (only a Sith deals in absolutes), engineers want to engineer.
There is no incentive for management to nudge the best performing engineers to teach their expertise in their craft[s]. A high-performing engineer "reflects good" on a manger. The way incentives are generally structured, this becomes a problem that perpetuates itself: Everyone in the management pipeline gets more money for the high performing engineer to keep engineering, rather than to teach.

Every single possible airplane maintenance operation is detailed on task cards that mechanics follow. Probably there is some small amount of tribal knowledge, but virtually everything is documented with step-by-step procedures, which includes the tools you need, every step, all torque values, etc.
It’s not like being an electrician or pipefitter where you have to make your pipe or conduit get from point A to point B by following the construction code, airplane safety is crucial enough that documenting and standardizing airplane maintenance was done long ago.

Yeah, my great aunt's bridge partner's husband had a cabinet shop which I used to hang out in after school when I missed the bus --- learned a lot by osmosis just hanging out and helping and doing odd chores.
When he passed away, his wife rented the shop out, to a drug addict who pawned off all the tools he could sneak out in his car.... when there was eventually an auction, not much was left, but I did at least get to buy an (empty) toolbox he had had me assemble from scrap lumber (which I still have on my workbench as a remembrance).
That said, for a flip side look at this sort of thing, consider the case of Charles Babbage trying to get his Analytical Engine made and the dispute over who owned the tooling, him or Joseph Clement, with the latter winning because at the time, a workman owned his tools, even if they were specifically constructed for a customer's project.

This is relative. In two generations, the concept of "master craftsman" and longevity will have been forgotten and short term thinking will the be "norm".
It is only because we know and can compare that we judge.

Or closer to home: barely anyone remembers black and white television or the feeling it must have been to view the moon landing on one.[1] Cathode ray TVs have gone the way of the Dodos - good or bad? Who knows.
Whether a long term or short term outlook is better or worse, no one can tell because there aren't any goals nor targets to meet in evolution.
>barely anyone remembers black and white television or the feeling it must have been to view the moon landing on one.
Apollo 11 landed in 1969. Roughly a third of living Americans are of an age to remember watching it, and more than half of them would have done so on black and white TVs. (Color TV's didn't pass 50% of sales & ownership until 1972.)

I feel like some "old" people have the weird idea that "young" people are just clueless about anything older than themselves. Just because some technology is no longer in use, does not mean that you don't get in touch with it. You don't grow up in isolation. There are always museums and of course the appliances of your parents and grandparents, in this case their photos.
All the films beyond some point are black and white and it's not like there were no significant events during that time. (Although I have seen some color-pictures from the 1900s, but the majority of course wasn't.)
Sure, you only use the technology from the past 15-20 years in daily life, but I feel like the technology you get in touch with is more closer to 80-100 years.

Take a more holistic view, what happened to all the stars and galaxies?[1]
The spiritual acceptance of the inevitable end of everything isn't taught in any business school and we are left to face/cope with that ourselves. If maths/business is your poison for coping, then so be it. I dislike reducing every experience to numbers and graphs, profit margins, win/loss and them/us.
I guess I'm trying to say is that even the biggest profit will have no longevity when compared to, even just human history, let alone the history of the universe.
The thing is that profit is not the only reason people do something. Some people just like their profession, I would argue that this is kinda a requirement to actually become really good. So in order to actually matter for a good skill you must lack the very argument you argue with.
The leading of companies with people not actually skilled at the craft is still a historic anomaly.

When you look at indoor square footage per capita (so like include the average HNer's share of the Starbucks and Whole Foods they patronize) and square footage and compare that to unit development trends and look at the costs it looks like we're just building bigger boxes rather than more of them. Basically the same story of the winners carrying the average that you see in every other market segment. Real estate development is probably one of the best market segments that illustrates the "K shaped economy".
Likewise with medical. It's probably a fools errand to try and figure out whether wiping the elderly's asses is over sold or drugs are over sold and both sides claim they're creating Real Value (TM) and making people's lives better but when you zoom out and look at how much we pay for all that it's clear that something is very wrong and it's a monetary drag on us that prevents us from being to spend our money on hookers and blow and Big Macs (or whatever it is that we want to spend out money on).
I didn't mention the tech industry in my quip because it makes things people elect to use voluntarily (to an extent, try not having an email these days) rather than structures itself to essentially compel more money to be spent within it like the industries within real estate development and medical do.

But to me it's a world of difference between what you do on the computer so no, spending 12 hours in front of the computer was never boring, there are countless of different things you could be doing.
Then I caught myself thinking the same way about the fisherman that lives next door, who I pass every day and he sits and does something with his fishing nets. To me, it all looks the same way, so I asked myself how he can sit every day doing the same thing, over and over again. Asking him about it, apparently it's not so "the same" every day to him, as depending on the expected weather and what not, he prepares the net differently, and sometimes tries new things for various reasons. Maybe he is bored after all these years, I never asked, but I learned not to assume at least that things might look the same from the outside, but the person might be having a completely different perspective on it.
Like a taxi driver, it's just "driving all day" right? For a lot of people, seemingly this brings them a "no day is ever the same" experience and they love it and don't see any repetition, at least lots of drivers I've talked to felt this way.

If you're interested in commercial aircraft and their maintenance process, check out Stig Shift on YouTube. He's another AA mechanic based in LAX, and makes interesting videos with some technical deep dives interspersed with planespotting.
Possibly the website has been hugged to death, but the principle resonates with me from the headline. In the large and old enterprises I've worked with, there is such a stark shift from I suppose, lifetime service to the consultant economy as the workforce transition follows the boomer generation out, and forecasting where that might leave us.
Short term drivers like a bad quarter or to be seen "disrupting" as a measure of progress, rather then genuine demonstrations of skills, turf out tenured employees often mid-career.
Or perhaps being in the engine room of many companies, doesn't often give you the lifestyle you want anymore, so the race to the top is the optimal spot to go for. Even if it means going up and falling down a few times on the heirarchy, its worth it.
The value of the nature of not having custodians of certain crafts, like aviation or really at the guts of any industry, seems to me its really going to set us back towards really transactional style of operating businesses that are only financially engineered and not really innovating the product in a way they should.

I read this as American Airlines not offering sufficient retirement funding to it's staff that they have to keep working into their 90s

Somebody in his position (major crew chief, maxed out seniority) would've been making about 120k real dollars, plus his defined benefit retirement, plus flight benefits for him and family, for the past few decades. He spent his time off volunteering to fix museum aircraft so we can say he really really loved the work.

It seems like this guy just truly loved his work. It's ok to be inspired by his passion rather than immediately turning to the most cynical explanation for his long tenure.

Its a pretty classic orphan crushing machine example
One thing that can't be codified in procedures is what I call "situational awareness" for lack of a better term. I don't think you can learn how to work in a machine shop safely from a book. Or recognize when a complex design is heading towards being unworkable. In my organization, the older engineers have a sixth sense for projects that are going to be cancelled.
There's a reason why older drivers (up to a point of course) pay less for car insurance, yet the rules are the same for all of us.
Not to be negative about experts here, but of all industries, isn’t airline maintenance one of the most documented and standard procedure focused of them all? I would hope that someone maintaining a 777 doesn’t have to remember certain tricks or tips outside of what the manuals say, and when mistakes are found, they’d be noted, investigated and republished to all maintenance crews worldwide.
It doesn't matter how well you document things there will always be tribal / personal knowledge.
Even if stuff is written down you have to know where to look.
It’s a great story, but I assure you there is a pretty high percentage of airplanes flying with missing parts and systems placarded as INOP in both military and civilian aviation.
To reiterate, you CANNOT fly an airplane with an undocumented missing part. If the part is documented in the logbook as removed, and it is acceptable to fly that way, then it is not missing.
I have been building and maintaining commercial aircraft for a living for 30 years. What is your experience?
There were posters everywhere about "extra parts" they called FOD.
What's being ignored is the 1/100 of these stories where this judgement pays off, saves aircraft and lives that make the other 99 worth while.
That's one of the things I love about AI: It's excellent at figuring out where to look, because it can digest so many documents so much faster than a person.
It’s more true in aviation than anywhere else (except maybe space flight), but still.
Just making a point that everyone else’s job always seems simple from the outside.

It takes also many years of study before they will let you touch any living person with your scalpel, and then many years of apprenticeship with actual surgeons when you do touch people with your tools.
I can imagine maintaining a big jumbo jet also requires some specialized practical knowledge you cannot acquire just by reading books and looking at nice little videos.
The problem is not to explain things when everything works perfectly. The problem is getting the ability to diagnose the root causes of defects using all your senses and your intuition. That is not taught in books.
That doesn't apply to private hire vehicle drivers afaik.
Augmented reality glasses, coupled with an AI that can interpret vision would seem to be useful here then.
There needs to be SOME accountability. "Oh, but my glasses told me to unscrew this bolt, I was just following orders." is not how I want the future to be.
I guess it would explain those small insignificant issues, however:

I guess a more relatable way of conveying this is that you can have the recipe from a michelin star chef, but you're still not going to get anywhere close to michelin star quality.
I hope you're right :) You probably are too. But even with that, there is a reason it's a profession and not something we ask gig-workers to do, it takes expertise and skill like any other skilled work, even though all the literal actions one might take is technically written down somewhere. Even in such industries, experts would get "hunches" about what is wrong, and are able to quicker pinpoint issues, and similar things. Or "getting a bad feeling" before something is actually evidentially bad, which prevented human disaster more than once in history.
I think if you consider that the job couldn't be done by just anybody who can read and follow instructions, then it might not be as easy as just "follow what the manuals say" and in those cases expertise, knowledge and experience matters a great deal.
Often it is not possible to separate the technique from the man. Things like riding a bike or flying a helicopter come to mind. A lot of what makes a master good cannot be written down anywhere. There isn't anything tangible to actually lose.
How would you write a document that describes to someone how to ride a bike or dig holes efficiently? You could explain the principles and general ideas, but the apprentice is going to need to get scraped up a bit before they actually learn anything that matters. The apprentice willing to suffer repeated failure is where most of the heavy lifting occurs. The master is mostly a backstop to keep the apprentice alive.
You don't. You put these people together for some years to work on stuff together, and a small percentage of this "intangible" feelings, knowledge and experiences you cannot write down somehow magically passes over to the other person.
Of course, the apprentice will still require their own repeated failures and uphill battle even getting close, but having someone who mastered the craft near you as you go through this, makes the whole process a hell of a lot faster.
The amount of tacit knowledge I am applying to the architecture of my projects is probably too deep for LLMs to even approach, IMO. It takes very little to have Opus or even Fable make a mess that is obviously bad to anyone who understand even the first thing about effective software architecture.
Worse is that they who have the knowledge don't realise that others don't know what they know, it's completely automatic and ingrained to the owner.

It's unclear whether these sort of players will do as good a job at handing down their knowledge though. Think about how little you remember, in much detail at least, about stuff before you were 12 - and now imagine you were already master strength by then, let alone a grandmaster. I'm a later starter and can still vividly remember when I barely knew how the pieces moved, and I think that gives me a huge edge over most players in terms of teaching.
Your bicycle case is a great example. People don't learn to ride a bike from a book. They receive in-person instruction of exactly the type the comment you're responding to was writing about.
To relate this back to the comment thread, people don't even always know the full extent of what they have learned.
The point of hiring someone specifically to do this is that he might simply want to keep on working, uninterrupted by apprentices or other demands, so the recorder must be a second person dedicated to knowledge maintenance.
This is, pardon the cliche, the exact type of “outside of the box” thinking that is completely impossible in shareholder-driven (or PE-driven) corporate America.
More and more I believe that we associate people with great ideas not because they were exceptionally capable of great thought, but because they managed to impose their ideas upon others through force of will, political chicanery, and sorcery.

Just a couple of examples.

Generally speaking (only a Sith deals in absolutes), engineers want to engineer.
There is no incentive for management to nudge the best performing engineers to teach their expertise in their craft[s]. A high-performing engineer "reflects good" on a manger. The way incentives are generally structured, this becomes a problem that perpetuates itself: Everyone in the management pipeline gets more money for the high performing engineer to keep engineering, rather than to teach.
Hopefully you are apprenticing many junior engineers!
Every single possible airplane maintenance operation is detailed on task cards that mechanics follow. Probably there is some small amount of tribal knowledge, but virtually everything is documented with step-by-step procedures, which includes the tools you need, every step, all torque values, etc.
It’s not like being an electrician or pipefitter where you have to make your pipe or conduit get from point A to point B by following the construction code, airplane safety is crucial enough that documenting and standardizing airplane maintenance was done long ago.
When he passed away, his wife rented the shop out, to a drug addict who pawned off all the tools he could sneak out in his car.... when there was eventually an auction, not much was left, but I did at least get to buy an (empty) toolbox he had had me assemble from scrap lumber (which I still have on my workbench as a remembrance).
That said, for a flip side look at this sort of thing, consider the case of Charles Babbage trying to get his Analytical Engine made and the dispute over who owned the tooling, him or Joseph Clement, with the latter winning because at the time, a workman owned his tools, even if they were specifically constructed for a customer's project.
It is only because we know and can compare that we judge.
Remember, when we were hunter & gatherers, before becoming bound to the land and tilling that land, we had different gifts and talents that have all been lost. For better or worse.
Or closer to home: barely anyone remembers black and white television or the feeling it must have been to view the moon landing on one.[1] Cathode ray TVs have gone the way of the Dodos - good or bad? Who knows.
Whether a long term or short term outlook is better or worse, no one can tell because there aren't any goals nor targets to meet in evolution.

Apollo 11 landed in 1969. Roughly a third of living Americans are of an age to remember watching it, and more than half of them would have done so on black and white TVs. (Color TV's didn't pass 50% of sales & ownership until 1972.)
I feel like some "old" people have the weird idea that "young" people are just clueless about anything older than themselves. Just because some technology is no longer in use, does not mean that you don't get in touch with it. You don't grow up in isolation. There are always museums and of course the appliances of your parents and grandparents, in this case their photos.
All the films beyond some point are black and white and it's not like there were no significant events during that time. (Although I have seen some color-pictures from the 1900s, but the majority of course wasn't.)
Sure, you only use the technology from the past 15-20 years in daily life, but I feel like the technology you get in touch with is more closer to 80-100 years.
Also the BBC still issue black and white TV licences, I suspect my phone is eligible for one! Still about 3.5k of them working apparently.
Nobody plans for decades because nobody can afford the risk.
On a personal or organizational level there is no point in making investments that will turn profit over the course of decades if over the ~5yr horizon there's there's always the looming risk that the government will kick your craft out of the country at the behest of the people.
What happened to all the men who specialized in casting steels? What happened to those facilities? What happened to those companies?
The math is simple and they teach it in every business school in the country.
Of course we can apply the laws of physics and the theories of maths onto everything we see and experience around us but does that make them so - those experiences.
> What happened to all the men who specialized in casting steels? What happened to those facilities? What happened to those companies? Nobody plans for decades because nobody can afford the risk.
Take a more holistic view, what happened to all the stars and galaxies?[1]
The spiritual acceptance of the inevitable end of everything isn't taught in any business school and we are left to face/cope with that ourselves. If maths/business is your poison for coping, then so be it. I dislike reducing every experience to numbers and graphs, profit margins, win/loss and them/us.
I guess I'm trying to say is that even the biggest profit will have no longevity when compared to, even just human history, let alone the history of the universe.

The leading of companies with people not actually skilled at the craft is still a historic anomaly.
Would we have nearly as many slime-balls scheming up ways to plaster ads upon everyone's eyeballs and record our every movement and click if not for the money in it? At a societal level almost nothing ever gets done at scale if there isn't money in it. You remove the financial incentive and things atrophy, new investment stops replacing old, etc.
People also lend money and invest in equities like index funds to plan for decades.
You cannot eat real estate or stock options, the medical industry is a drag on us all though obviously you can cherry pick examples where things don't look perverse.
The things they create (and not exclusively they, obviously the country as a whole creates too) directly lead to the share price increases and dividends that allow many or most people in the US to maintain purchasing power.
When you look at indoor square footage per capita (so like include the average HNer's share of the Starbucks and Whole Foods they patronize) and square footage and compare that to unit development trends and look at the costs it looks like we're just building bigger boxes rather than more of them. Basically the same story of the winners carrying the average that you see in every other market segment. Real estate development is probably one of the best market segments that illustrates the "K shaped economy".
Likewise with medical. It's probably a fools errand to try and figure out whether wiping the elderly's asses is over sold or drugs are over sold and both sides claim they're creating Real Value (TM) and making people's lives better but when you zoom out and look at how much we pay for all that it's clear that something is very wrong and it's a monetary drag on us that prevents us from being to spend our money on hookers and blow and Big Macs (or whatever it is that we want to spend out money on).
I didn't mention the tech industry in my quip because it makes things people elect to use voluntarily (to an extent, try not having an email these days) rather than structures itself to essentially compel more money to be spent within it like the industries within real estate development and medical do.
>Nobody plans for decades because nobody can afford the risk.
I respect people who can do it, who can live a simple life doing the same thing every single day and be happy about it. Sometimes I wish I had that ability. But it is very much _not_ me.
Then I caught myself thinking the same way about the fisherman that lives next door, who I pass every day and he sits and does something with his fishing nets. To me, it all looks the same way, so I asked myself how he can sit every day doing the same thing, over and over again. Asking him about it, apparently it's not so "the same" every day to him, as depending on the expected weather and what not, he prepares the net differently, and sometimes tries new things for various reasons. Maybe he is bored after all these years, I never asked, but I learned not to assume at least that things might look the same from the outside, but the person might be having a completely different perspective on it.
Like a taxi driver, it's just "driving all day" right? For a lot of people, seemingly this brings them a "no day is ever the same" experience and they love it and don't see any repetition, at least lots of drivers I've talked to felt this way.

It's because management didn't value it. They put the veteran on on more jobs rather on moving them to training, because short term it's more profitable, and mid term it's easier to poach veterans off competition rather than train them in house

Short term drivers like a bad quarter or to be seen "disrupting" as a measure of progress, rather then genuine demonstrations of skills, turf out tenured employees often mid-career.
Or perhaps being in the engine room of many companies, doesn't often give you the lifestyle you want anymore, so the race to the top is the optimal spot to go for. Even if it means going up and falling down a few times on the heirarchy, its worth it.
The value of the nature of not having custodians of certain crafts, like aviation or really at the guts of any industry, seems to me its really going to set us back towards really transactional style of operating businesses that are only financially engineered and not really innovating the product in a way they should.
just random thoughts around how to have a fulfilling career, when most of the effort is in sales & marketing, and not much in operations when the funding pot gets allocated across a business.
You can hover over the "hours ago" link and the timestamp does not match the title.
Why is the timestamp of my comment (and many others) of this post manipulated? Was this post recently merged with another duplicate?
Interesting you've been here at least since then and haven't noticed it before, happens relatively often, dare I say at least once a day?
I'm guessing HN either by choice or by accident shows the "original timestamp" in that title attribute, while the user-facing rendering shows the newly bumped timestamp.
