You can add "before:2023" to filter out a lot of it when searching. Doesn't work for everything, obviously you won't find yesterday's news or info on the newest games that way. But I think it's good hygiene for very broad topics. Beyond that, if it recommends me some new channel, I check the account history and try to see if they were already uploading similar looking videos before the early 20s. If not, I treat it as suspect.

Tho even before the recent AI boom, there was plenty of other low effort (via other means) slop out there.
