For example, my hobby is welding and I want to get playing some welding playlist in my garage while I am welding, instead of some music. But I do not want to chose what welding video to watch because I am already doing some welding and do not want to distract from metals to computer. That welding videos are needed for me not because I can not weld but because there might be some useful ideas hidden in those tons of speaking. Autoplay is not an option for me because there is a difference between selected videos and proposed.
geesh.
but as with any data set the more you put into it the more relevant data you'll get out of it. subscribe, thumbs up or down, don't recommend channels.. eventually you'll get to the point where the system suggests stuff you actually care about.
in your 2nd paragraph it sounds more like you want podcasts not pre filtered clickbaity youtube videos. Especially if you're looking for nuggets of information. It would probably faster to read the transcripts / comments to gain those insightful ideas. Especially if the idea is only 30 seconds out of a 30 min video.
