Actually, joking aside, Sony's approach seems to be built around relationships with the stars rather than the directors. If you want a deep dive into the subject, I recommend Ben Fritz's The Big Picture, which draws on interviews and the big Sony email hack for source material.
Arad tried but it was really David Maisel who got the banks to fund the movies. Highly recommend this book, it has two great chapters on the beginnings of Marvel and the Spiderman Homecoming story.
Even if the money is there, there still needs to be distribution, marketing.
The studio system will still be the majority of media we know about in a decade where TV and Films are concerned.
I highly recommend everyone read The Big Picture: The Fight for the Future of Movies by Ben Fritz
Streaming is just consolidating what the studios already started.
Currently reading this, I've read 2 chapters so far on the creation of the MCU and its impact on Hollywood.
