Adding Whisper subtitles was really easy and they're dramatically better than the automatic Google ones (I did it via https://github.com/abdeladim-s/subsai, which was trivial to use). So there is now a reasonably good transcript available in the video comments.

Otter.ai does a remarkably good job.

Disclaimer I said, and disclaimer I meant. That was a warning.

I guess the difference is how we are watching things.

You are probably looking for an answer to a certain question. Or want something that you can rebuild at home. Or want to consciously spend the next hour actually extracting valuable information (or enjoyment) from a video.

But here I meant it more like: When I get home from work, I can start up my PC, open YouTube and start watching Hjalfi's new video, while simultaneously going about my usual routine of reading/answering mail, doing some coding, playing a game, etc., all while watching the video on a second display.

i.e. for me it's more like streaming music in the background, except it also has video. Of course you probably can't do things that require you to be super focussed (and in those cases, I actually pause the video), but in all other cases (casual gaming, coding things like Advent of Code, etc.) it's pretty nice.

I used to unconditionally hate videos, especially tech videos, for exactly this reason. Later I realized that these videos are made for a completely different audience - most of them are meant to be watched while sitting on a sofa with some coffee or popcorn on a Sunday evening, rather than technical communication. It's great that you can coincidentally learn something while watching it, but it's primarily infotainment. Meanwhile, clicking Hacker News or Reddit links is the modern equivalent of reading newspapers and magazines, with an audience who demands more efficient communication.
