I agree with everything but the last sentence. Pretty much every industry that is forced to grow indefinitely eventually shows the same pattern of (either diversifying or) cutting expenses at the bottom to maintain growth at the top. It's obviously unsustainable and nonsensical. It's only becoming obvious now because technology has made it possible for the largest players to saturate their markets. (And, far from "curing" it, the potential of AI only exacerbates the market saturation problem.)
So we're finally seeing what should have been obvious all along. To me it seems clear that corporations need to start thinking about growth differently in order to come up with genuinely sustainable business strategies. In the short term they may simply have to fail. Netflix could fail tomorrow with minimal impact on viewers. And if their corporate dynamics demand that they must either lower costs or fail, then failure is likely inevitable since they obviously can't reduce costs forever, regardless of the outcome with SAG-AFTRA/WGA today.
