You’re making what seems like a zero sum assumption. I am still using my M1 MacBook for work. I have a first version Mac Studio at home and countless other devices laying around. The world will continue to move forward and yes purchasing will slow down but folks will still be using their existing phones, laptops and other devices.
I don’t think Apple is gonna go home because of the three-headed memory cartel, since they didn’t spend/burn billions (one trillion?) of dollars on AI, I think they will replace the cartel in-house, Intel is out and Qualcomm is on the way out, the three headed cartel can follow them.
