I think another issue is that so many celebrities are increasingly so fake in everything they do. Limited life experience, limited ambition and drive, and still being paid the big bucks in spite of being soulless husks compared to some of their predecessors.

And top of that they've become the most outspoken and whiny bitches, despite being well off financially and career-wise. It's of little surprise that "influencers" and vtubers seem to command just about as much attention and respect now, comparatively.
