Install browser extensions that replace all video thumbnails with randomly selected video frames. All of a sudden, the startpage looks like a bunch of car salesmen, nothing but talking heads. No polish, no arrows. Did wonders for me. I think the one I use is called DeArrow, and it allows you to hide shorts, comments, recommended section and more. Really useful.

Get out of algorithm and suggested video streams completely. Use NewPipe or something and only use subscriptions or intentional searches.

The kind of content and creators I watch are mostly on Nebula. I'm spending more and more time on Nebula and away from YouTube.

Interesting technique!
