I didn't watch the links you provided, as I stopped watching youtube about a week ago. It's full of AI crap and useless content. The videos suggested to me are waste of my time.
I don't really agree. I watch plenty of youtube channels where people discuss technical topics, engineering, psychology, and other subjects, and I haven't noticed AI-generated content being a significant problem there. Most of what I watch is made by real people and is genuinely informative.
As for AI itself, I've actually come across quite a lot of AI-generated music on youtube that I genuinely enjoy.
For example:
In my opinion, the biggest problem with youtube isn't AI - it's advertising, especially if you're using the official app or Chrome without uBlock Origin.
With ads enabled, youtube has become absolutely unusable. Videos are constantly interrupted, and you're repeatedly presented with content you're not interested in. On the mobile app it's particularly bad, to the point where watching anything becomes frustrating. In Chrome, ads don't take over as much screen space, but they still appear frequently enough to seriously disrupt the viewing experience.
On the other hand, using firefox with ublock origin provides a completely different experience. Without constant ad interruptions, youtube becomes much more enjoyable and practical to use.
Also, if you're signed in to youtube, don't forget to use "Don't recommend channel" and "Not interested" whenever you come across content you don't want to see. Over time, this improves the quality of your recommendations and helps filter out a lot of crap videos.
