What an idiotic take.

"Celebrity" worship has existed since the dawn of cinema. Star Power is what brings people into the theatres.

People have always wanted to know all the salacious gossip about their favourite celebs, and that's what makes Hollywood go around; they want to fell like they "know" their favourite actor/director etc...

For example:

• The only reason anyone remembers "Mr. And Mrs. Smith is because its the movie that gave us Brangelina and broke up Pitt and Aniston.
• "The Whale" was a mediocre movie at best that won awards in part because of Brendan Frasier's comeback after being shunned in Hollywood.
• Martin Sheen being legitimately drunk and cutting open his hand created an iconic scene in Apocalypse Now.

I could go on and on. Point is, actors being themselves into the roles that they play.

You can't replace that with soulless homunculi that have no life off screen.
