Something interesting to note, is that while "Hollywood" is fast losing its status as the nexus of the traditional film / tv industries, LA in the broader sense is already very well established as the global (Well at least "Western") hub of the content creator economy. Literally thousands of wannabe / up and coming YouTubers, Tik Tokers and "Influencers" of all sorts are packing up their lives and moving to LA every year in order to be closer to each other, and to the talent pool of cast-off film and tv folks that live in LA.
The "Cost disease" seemingly hasn't yet infected that industry at least (Or the infection is still in its early incubating stage) though I think that's in large part due to the fact most of the content creators aren't working within the established industry framework, but rather are intentionally trying to work outside of it, in order to avoid paying union rates.
$10k rent on a hollywood hills mansion isn't so bad when you have it sleeping 10-15 20 year olds.
