The dude invented the modern blockbuster. What more do you want from him? He has to revolutionize cinema AGAIN? He said in the making of Indiana Jones that he thought after Last Crusade that it was time to go grow yo and make more mature movies, which is sorta what he's been doing now. Why would he feel like he has anything to prove to go searching for some script and method of innovating the industry yet again so he can be hailed for doing so once more when all he wants to do is make the kind of films he wants to make? Remember, he didn't even want to make Indy 4 and clearly passed on Indy 5. He definitely gets offered every big movie in Hollywood before everyone else and passes, so what he wants to do is up to him.

Dude is still insanely sharp. He doesn't even storyboard most of his shots. Just shows up and shoots. You can't fuck with Spielberg. This entire premise is stupid.
