That's true and yet I'd say that's not my problem? The market will be fine. If anything that means more software work for me. New opportunities will arise. People won't buy a new phone every year for a while (which is objectively a good thing!). The M series MacBooks are so good now there's virtually no reason to upgrade to M2 or M3 if you have the M1 (like in my case). I fully expect to use this computer for the next decade. My desktop PC is basically unchanged since I built it in 2016 (+1 extra SSD I've added after, but that was it). The i7-6700K in there is still chugging happily along. Apple have more than $100 billion of cash at hand. They will be fine no matter what happens. It's not like they didn't change chips before :)
