From when I still watched her, Superdeterminism seemed to be her thing. Its a non-theory, totally unprovable. I don’t think she’s a MOND believer, could be wrong though but either way she’s not a cosmologist.
Oh yeah it wouldn’t change a god damn thing, arguing about it would be literally pointless. Same thing as arguing against free-will, either it exists or it doesn’t. Debating it is pointless, finding out one way or the other is pointless since in both cases nothing changes.
She is truly awful, her take in her own field is extremely dumb but it’s her takes in other fields that are even worse. Like a lot of science YouTubers she doesn’t stay in her lane, she thinks the fact someone gave her a phd for her ridiculous idea of superdeterminism gives her license to opine about other field she knows fuck all about.
If you can find any video of hers from a field you have first hand knowledge about her takes are wrong, and not just wrong, but that special kind of wrong where you completely misunderstand the basics of something and then extrapolate out from there the stupidest fucking conclusions imaginable.
