To be honest, a lot of the YouTube content creators, especially the most successful ones, actually moved to LA and Hollywood already, suggesting that its not Hollywood itself, as a place for developing fresh ideas, that is dying, but its more established institutions. I would say that if you are in LA right now, there is no end to the amount of young people ready and willing to work on some creative entertainment project, but the market is YouTube, and the biggest studio is MrBeast's (among others).
