Youtube was a jewel. Sign out, clear your cookies, and take a look at the default recommendations to a new user. It's a cheap TikTok clone.

It's a shame, because I've learned so much. I have also wasted a lot of time and attention there.

Edit: I should clarify "learned so much". I learned a lot by watching knowledgable and skilled people share their experiences and wisdom. However, there comes a point where you are just watching someone else lead their lives, instead of leading your own.
