You can't fix social problems with technical solutions.

Twitter is by design a melting pot of opinions because of it's global access to anything, which is good and bad in it's own ways. Until this design changes, there is not much you can improve on fundamental levels. And any fundamental change would mean for twitter to stop being twitter. Then you could also just switch to your personal forum, blog, discord or whatever controlled safespace you prefer for your content.

Thouhg, this was with twitter always the case, it's nothing really new. Maybe it's your perception which changed, or your bubble which has moved? Maybe you are at the point of being "to old for this shit" now?
