@rubenbolling Also a big fan of Carroll and his books (and podcast). As a very rusty ex-physicist (dropped out halfway through grad school with an MA) I suspect the debate over interpretations of QM may be settled by increasingly larger "Schrödinger Cat States”: macroscopic objects put into quantum superposition.(e.g. https://apple.news/AZQwoWZiGSNCWR6faczustA). At some point either this will fail, or it will become undeniable that there's no limits to quantum superposition.
