There won't be any alliances between studios and content generators to battle Big Tech. There's too much consumer profit in this industry and the money isn't being shared evenly on any front.
Big Tech's AI may be a looming threat but there's a bigger one that we often ignore; the investor class.
Wall Street is the hidden empire in this battle. The investor class has spent decades courting the studios and it shows in how they handle (or mishandle) IPs.
Consumers aren't really the main focus of the entertainment industry; profit and shareholder satisfaction is. The studios have their creative financing and accounting that allows them to make money whether they have a hit property or not.
Actors and production companies are never going to be on the same level of power in this battle and shareholders are never going to give up their dividends or holdings to save the industry.
The very same people who are financing studios are pumping all kinds of money into AI in hopes of tapping a new gusher. Investors are all about conquering new worlds.
Wall Street is the fleet out in geosynchronous orbit watching the natives battle it out on the beach as the Europeans wait in their ships off shore. AI is just the droid army waiting for their orders.
