After some pondering, I've come to consider it a generally positive thing. If I compare watching a 1x video to my reading the transcript, I am reading very much faster than the person can normally speak. Cranking the speed up makes it so the video much more approximates a reading speed. You still don't get as much random access and I can generally still read at a speed where I wouldn't be able to comprehend the speech if it was keeping up, but I think being able to handle increased information density is generally a good thing. It also tends to filter out videos that are just noise and flash and such, because any video tuned for simple tickling our lizard hindbrains at 1x is much less appealing at 2x (because if it was more appealing at 2x, that simply would have been the original speed it was served at).

It is also a side effect of the fact that frankly a lot of stuff on YouTube doesn't actually need to be on YouTube and is, as I mentioned in my first post, really just a podcast with a video track because it has to have a video track to be on YouTube, but that is perfectly ignorable. Even channels as high quality as Practical Engineering are (guestimating) something like 80% stock footage and 20% something he actually created that is useful and germane to the topic.

I often have a hard time dealing with videos at 1x as well but it's not like it has impacted my social relationships or anything. I don't perceive normal people as speaking slowly now or anything like that. Somehow my brain has this segregated, and I phrase it that way because it's not like I can consciously take credit for it, I didn't do anything, it's just happening naturally.
