I think it also has a huge effect on sports. Especially the ones that aren’t on TV. When I did martial arts in the 90s it was super hard to find recordings of good Muay Thai or kickboxing fights. So you had to figure out things for yourself very slowly instead of seeing how the world class guys do it. Today’s youth can watch the best in the sport from all history and learn things way faster.

Tetris is another great example of how competitors are using YouTube to rapidly progress in skill.

While visual learning through YouTube is a step up in terms of tacit knowledge transmission I think the example of becoming a world class athlete by watching YouTube videos is probably really an exception and mentorship and a comprehensive environment to learn in are very important.

Samo also lists (heart) surgery as an example and I think it would be very hard to learn this at any level of excellence from footage alone. (obviously also hard to test given the lack of volunteers I imagine). But there's a huge tactile component that just gets absorbed by osmosis in a real world setting and that's hard to replicate from a screen. Same with woodworking and some of the other examples given. Even labwork in fields such as chemistry has a surprising amount of 'art' to it that one wouldn't expect just from observing.

I am essentially a self-taught EE thanks to the internet.

My wife’s business has a number of self taught engineers. As management (everyone management started as an engineer), they have full faith in these people and love them. However, it causes them no end of pain that they never got their degrees as client contracts often require a credential to bill at higher rates. For the ones that are willing, they’ll gladly sponsor a degree pursuit and pay them more at completion, b…

I have associates degree in electronics tech and did go for my full engineering degree, but failed out...twice. I cannot for the life of me reliably pen-and-paper-clock-ticking solve complex equations. I even payed out the ass for a top tier tutor, no luck. I very firmly reached the "Maybe this just isn't for you" point. But with my own work and in my job, being really bad at high level calculus or diff eq has never even cropped up much less been a detriment (Well it does crop up, but in the SPICE simulator/circuit simulator).

Oddly enough the engineering lead here is an uncredentialled engineer, but he was also the first employee 25 years ago so I suppose he is grandfathered in. Not that he doesn't deserve it either, he is wildly knowledgeable and capable.

There are many lectures and conference talks from university professors who are at the top of their field on YouTube. You might be able to find better content than what's available in your local university class. For example, Robert Sapolsky's lecture series on Human Behavioral Biology at Stanford: https://www.youtube.com/watch?v=NNnIGh9g6fA&list=PL848F2368C... Stanford and MIT both have lots of lectures on YouTube.

Oh I know, but there are also a lot of people making claims to expertise they don't have and spreading lies. Some of them are real experts in other fields and so have respect there.

It's generally pretty easy to spot the fakes if you have a basic understanding of the field and are just researching for specific details. Frankly, for the stuff I typically look for, there are surprisingly few fakes to be found. This may change with YT deprecating the down-vote arrow.

I just tried to figure out what people actually watch on YouTube a couple of days ago without much luck. I came across some numbers but they only divided the videos into very broad categories like music, entertainment, education, and others or something like that. Is anybody aware of a more detailed look at this?

Yeah, you're right. Wikipedia lists the most popular channels, and they're pretty much just entertainment and music. Then again, as near as I can tell, that's exactly what they are. Even the one listed as education is just music/entertainment for children.

Have you considered taking up programming now? In many ways, age is just a number.

Yeah, I have. The problem is that I really do love electronics. I am a decent C programmer, for embedded applications at least. I have never written an actual PC program though besides tutorial stuff.

A friend of my did a crash course boot camp for js, and did eventually get a good job out of it. Maybe I should think about doing the same.

Not only that, but for example for table tennis there are hundreds of high-quality teachers showing you the basics of the sport, sharing tips on how to get better, giving you professional advice on how to train and much more. It is a lot easier nowadays to go from completely new to decent or even "good" in a specific domain by following some simple visual instructions.

Any channels you might recommend?

Ahh the good ol "medicine is Art and science" keeping the physician cartel alive and well, with no competitive risk from scientists and AI.

I know my son was at risk of worse outcomes if not for me researching the relevant scientific papers online. (Tongue Tie, surgery vs laser, physician recommended surgery because it's done by a surgeon not a dentist. Outcomes are worse with surgery)

It's about time we move to evidence based medicine and revoke licenses from traditionalists.

Youtube deserves no credit: they do nothing to make educational videos more discoverable, they cannot even categorise them properly! My 'feed' is filled with videos I already watched and typically the only way I discover new content is linked from HN or other sites. Neither does Youtube treat their educational creators well - as far ad they are concerned, 'influencer' reviewing funny viseos has more value than educat…

You're using YouTube wrong. I dunno. For me, YouTube serves me up so much educational content i want to watch that there is over 100 hours of content in my Watch Later. And i do very often go through the videos it gives me but it never ends. YouTube is a tool, you have to do a bit of curation so it learns what you like and dislike, and then it just delivers an unending firehose of content matching that. And if what y…

I dunno what i am doing wrong, but my youtube feed is a barrage of things I've already watched, the only way for me to get something new suggested that's not garbade is to spesifically search for it.
