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. So I expect the next gene…

I'm learning how to drive a Porsche 911 cup car in sim.

There's this guy on YouTube who races the car in both real life and iRacing, and he explains how he drives the car fast in both contexts.

His insights probably saved me a lot of work of figuring it out myself.

Well, I had a toilet problem a week ago. Looking it up on YouTube, I found a plumber who demonstrated a solution. Five minutes of work and the problem was resolved. IDK how much I saved, but at least 2000 CZK (approx. 80 dollars). Not to mention that I didn't have to wait for the plumber to arrive, which would take a few days, probably.

My YT fix tale: friend was throwing out an LCD TV because of weird colours, like solarization. I asked him for it, spent an hour searching youtube and found a TV engineer video with a likely solution: unplug the data cable where it feeds into the screen and scrape it clean. 7 years later and the TV is doing daily duty as a monitor for watching streamed content. I clean the cable once or twice a year, and one time had…

I'm not actually sure if I ended up looking at YouTube or just regular old web results, but my personal internet trust fall was replacing an old window with a new one, where the steps went: 1. Go to store. Buy a window, some 2x4s, and some plywood sheeting. 2. Rip giant hole in the side of my house, removing the old window and everything within about 3 feet of it. 3. Google [how to frame a rough opening for a window]. 4. Follow the instructions.

Granted, I already had some prior knowledge here -- I knew the term "frame" and "rough opening" -- but I was still amused with myself that I left an "acquire information about how to complete my task" step until the middle, when I had a giant hole in the side of my house.

Unfortunately it's being killed by the obnoxious advertising, which is growing far faster than the value of the content (it's already past my personal tipping point).

At some point we can hope that hosting is cheap enough we can all host our own videos, that search engines will find our content (without any favouritism) and that such an outcome will actually be legal.

It's a shame that nobody but Youtube can afford to host videos at a loss year after year. I could vent for an hour about why I dislike the company: they are a privacy abomination; their moderation is incompetent; the way they monetize is unethical. If there were a worse steward than Youtube to store the bulk of humanity's video, I can't think of who it would possibly be.

Are they so expensive to host yourself? Sure the picture quality won't be as great but with modern codecs it doesn't seem like it would be much worse than the average web page.

It’s not impossible, but I think it’s about 128 minute-views per GB and $0.01/GB? Which would make hosting e.g. Issac Arthur’s YouTube channel cost in the order of $200-$300 per video uploaded, which I would hope is small for him given how many volunteers he gets and the sponsor messages, but might discourage future versions of him from getting started.

Scott Manley’s channel looks like typically more views and shorter videos, so would probably be similar hosting costs. Would he still be able to do his thing without YouTube? Or Robert Miles (the AI researcher, not the famous one I’ve never heard of before updating this comment because I’m not into music)?

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.

you might want to check out the odin project... seems fairly high quality. or if that's not your jam i'm sure you could find a book or a course on something like coursera or udemy with varying success....

Oops, what I had in mind when I wrote the comment was the expense of hosting a vast repository of videos (eg: Youtube, Vimeo, Twitch, etc). I didn't mean the modest cost of an individual just serving their own content.

I had a motor issue with my dishwasher. With the help of a Youtube video, I was able to disassemble the full machine, identify the issue, and put it all back together. I don't know what going rate's are for fixing dishwashers, but I am guessing at a minimum I saved $200 bucks.

I learned a lot about knots and anchors on Youtube, and as a climber sometimes my life depends on it. But of course you should take actual lessons from instructors before using youtube as a resource.

I feel like people are too afraid of saying that you can learn dangerous topics without a proper teacher. IMO it holds people back. I'm a completely self taught outdoor climber (with the exception of a lead belay course indoors) and have worked up to some pretty advanced stuff. Trad, big wall, self-rescue, etc. Youtube was a big part of that. You can watch videos published by authoritative sources, cross reference th…

But are you the exception or are you the norm? I agree that if you seek out the right information - you can learn about all the safety concepts. I would say climbing is fairly intuitive and follows some basic rules.

But I've seen my fair share of people setting up american death triangle or threading ropes directly through the metal anchor. I've seen people using daisy chains as personal anchor device or taking hands off the grigri.

I fall on the side of holding people back is better - but who knows, maybe not

> But I've seen my fair share of people setting up american death triangle or threading ropes directly through the metal anchor.

Do you think these people have spent even a second doing any actual research on Youtube or otherwise, though? I have a hard time believing there are any Youtube videos suggesting the use of the American Death Triangle or threading ropes through the fixed anchor chains. Not using a daisy chain as a personal anchor is basically a meme at this point in any climbing forums.

In that case, it seems like the real thing to suggest is that people not just go out there and wing it. It's not that Youtube has failed them in that case, it's that they didn't even use it.
