Your concerns about the need for an algorithm is correct.
But, instead of “personalized content”, users should be able to make their own algorithm, with subscription and filter lists. I use uBlock Origin to block content you named as ‘tribalist’ (good take!).
But maybe I’m more sensitive. I don’t find Lemmy boring, I can lurk here for hours. So I also blocked the ‘prev/next’ buttons just to stay on the first page (I’m an eccentric person).
