I don't usually go to youtube for entertainment, but I do frequently use it to see how to do a specific task, or learn a new skill of some sort - and I find the ads boring and off topic, and not something I am interested in at all, usually. I skip them if I can. Or just turn off the sound and wait them out.

Youtube just amazes me that it makes the money it seems to, if its algorithms think that I am even mildly interested in the ads I am shown -

I think they need new algorithms, but they seem to continue to make lots of money.

I do agree, their ads are annoying, not useful, or endearing.
