One way that works moderately well is to mark certain topics as not interested when they are presented and like and watch the other topics for a longer time.

I've used the above to keep my YT landing page relatively clear of things I'm not interested in.

Once in a while it will suggest you a highly popular or interesting off topic item, but yea that is once in a while.

Basically what I'm saying is that we need to train their algorithm to our tastes through watching and marking things as not interested, don't show me this channel etc.
