Is the next George Lucas or David Lynch going to Come from Hollywood or the Self Funded Indie Sphere

Dumb, big-budget blockbusters have been a thing for a very long time (and some of them are well-made pieces of entertainment). But these mass-produced products have staggeringly large budgets that force studios into playing it safe. To counterbalance this, we have always had visionary directors that want to push the boundaries of the visual medium and the stories they can tell within it. This isn't a knock against the blockbuster. George Lucas would be considered one of those visionaries and he created the biggest blockbuster series of all time. But what makes Star Wars stand out is at the time it was a very different concept for film.
This generation hasn't seen the likes of its own Quentin Tarantino, David Lynch, Steven Spielberg (and the list goes on). Obviously, this isn't from a lack of talent. But I think it would be interesting to investigate where we think this generations visionaries that define that generation will be found.
Is it still possible to find directors that defy convention within the studio system? Or will people need to turn to the indie sphere, or possibly even Youtube creators as the next big filmmakers?
