Great if depressing summary. It remains to be seen who has the longer legs in this struggle - the writers and actors ( apart from the A and B Listers) don't have as deep pockets as the studios but then again the CEO's have their shareholders lighting their ass on fire if profits are in danger and that will happen as no new products are coming out that need to be written/filmed right now to be able to be released in the next weeks/months.
The damage is already done as no matter what happens there will be a large gap either this year or next without no new shows or movies coming out. Movies like Dune 2 are already being pushed to next year so they have at least something and this could increase. I don't see how both sides will come to a deal right now as they are in some areas so vastly apart ( AI and residuals seem to be chief amongst them) with only tiny movement. I thinl the WGA/SAG will have to move on some issues but others like AI usage, which directly threatens the livelihood of their members, can't be accepted under any circumstances.
This has the potential to be even worse than Covid and that was not that long ago.
