>>6408334In general I don't like removing them, it is usually when I do that they feel like their could come in handy, or generally for awhile I feel sorta like I am leaving something behind. If I needed to have it empty, then I would do this:
I would just create a new account
Freeze watched and search history,
Move subs I care about right now and move on using youtube on a new account.
Basically the old account then becomes a time capsule of sorts, I can also unfreeze history watch some videos and use the account in a way that modifies googles youtube proposed videos, so I can use that account for stuff I don't want to appear in my proposed videos.
The problem for doing this approach now is, that I liked so many music videos and have been using the "This video doesn't interest me" feature to completely remove music that are mainstream k-pop/American/polish garbage.
