As a finish carpenter for a number of years and having to deal with fixing homeowners attempts at doing their own remodel efforts based on them watching youtube videos, I've come to general law regarding expertise or 'how to' videos. There's an inverse relationship between quality of video and accuracy of information (or maybe just usefulness of information.) The majority of good polished videos have the least accura…

Someone highly skilled at one activity may only have enough content for a handful of videos, so there is also a tendency for the best videos to be old, have near zero subscribers, and be harder to find as a result.

I think it's especially interesting to look at how quickly people master a brand new field too, since it seems the timespan between a new hobby getting started and people making professional quality works in said area has gone down significantly too. For instance, my go to example are video game mods and ROM hacks. In the olden days, these communities grew quite slowly, and it took a fair amount of time for people to…

But those examples seem to be the result of more frameworks and tooling and boilerplate code that is already available that people can just build upon rather than delve into the inner workings and figure stuff out - rather than people learning to become experts much faster.

0 to 1 is the hard part.

I find that's true of most information. The higher the craftsmanship of the video, the worse the actual information being presented. Lectures, for instance, that are just a professor talking with his PowerPoint slides are almost always better than videos that put on a production with fancy graphics, jump cuts, and narration. Look at the news. The news with more spectacle tends to be of lower quality on average. Or an…

The more I think about it and reflect on my (computer science) education I think more and more the lectures are awful. It is only the ease/ubiquity of creating them that has kept them around. Fancy graphics is by no means an indicator of good information, but neither are lectures. It blows my mind that I can be taught programming concepts, say data structures, on a PDF. That is insanity, it is a total divorce from th…

Dijkstra and the European school took a dim view of gluttonous Americans who refused to do computer science if they didn't have an expensive computer in their lap.

Your pencils, paper, and brain are an executable environment.

Counter example: 3Blue1Brown.

In another field Wendover is pretty good as well and insightful. But you can probably count this kind of channels on one hand, per topic.

I’ve been working on my YouTube educational channel html/css/design ( https://youtube.com/FollowAndrew ) for a bit now. Pickup is slow, but it’s been fun helping a greater audience learn new skills!

I mean this in the kindest way possible, but do you think it's appropriate to teach such new CSS selectors? I just bounced around the slider on your featured video and I'm seeing stuff that only hits 85-90% on caniuse.com which is unacceptable for the apps I typically do. I still have a lot of IE11 that's used in large corps, etc. I'd LOVE to use things like grid-template but I can only imagine the fallout - I've only just been able to start utilizing basic flexbox.

It may just be different audiences/userbases, idk.

Any examples of great craftsmen with great video quality? I recently discovered the "Essential Craftsman" channel which seems to be pretty good all around.

I'm not sure what you're referring to but I'd be interested if you shared more. I don't know the references you make, though I do know the Alan Kay nano-Dijkstra quote.

I contest your second point, by definition my pensil and paper are not executable environments. My brain is, but this gets us into the game of "how much computer can you simulate with your brain."

Why do we play the game of simulate-the-computer? We've had computer environments for at least 40 years now that do that thinking for us, that answer our questions about control flow or definitions or alternate scenarios. We have them, they were thought up, written up and delivered. Yet as a field we value this stupid idea of working alone without help and don't teach these workflows using the computer as a partner. No, in 2019 if you can't do it on paper you don't know it. That's bullshit, yet here I am and I can do it on paper. I'm just sad for those who come after me and have to go through the same wasteful hazing.

As a die hard Jack Of All Trades handyman, I can't overstate how incredible a resource YouTube has been for me. You need to come at it with at least a small baseline of knowledge of what you're trying to attempt, good shop hygiene/safety habits, patience, a "measure twice, cut once" attitude, and so on. But once you get in the right mindset, there is just so much to learn there. I credit online resources for helping…

Do you have a list of videos/channels you've found useful for these projects? I would find it useful and I'm sure others would appreciate it as well.

I also think this is just how education works broadly. Whatever information has been printed in ten million textbooks and distributed across ten thousand public schools by a legion of educators is at a stretch mostly accurate. Our actual best understanding of the universe is whatever was just mumbled in a graduate seminar by a half-asleep emeritus faculty member who doesn’t really mind that nobody heard it, because t…

It’s a little different in that textbook companies can find authors who may or may not present the information well and then help them with editing and sales.

Also, in general, the very best books can only be written by a subject expert who can coherently hold enough of the subject in his/her head to find out how to express it. It’s rare but exists (tannenbaums operating systems for example?)

I’ve always wanted to try that out actually. I wonder whether it’s worthwhile
