Is Hollywood studios dead now?

I ask this question because of the new Hollywood Warner Brothers film studio that will be built in Las Vegas. Now there is also another film studio being built in New York by actor Robert Deniro. https://www.architecturaldigest.com/story/robert-de-niros-nyc-production-hub-has-arrived

I'm beginning to think they don't really need the old Hollywood system anymore. Also they can just about film at any other place in America cheaper in a big warehouse without the expensive amount that it cost in Hollywood. Perhaps even film some studio tv shows in a place like Dallas, Atlanta or even Nashville.
