Yup. I fear for my 2019 Mac Pro. Five digits of investment, and out of curiosity, I saw that Apple had reduced its trade-in "value" from $3,700 a few months ago to $1,100 now. Rather insulting, since they're still selling the same Mac Pro, and charging $3,000 for the RAM that's in this one alone.
I wonder if that is true. I hope so as I have a first gen M1 MacBook Pro and honestly it’s the best laptop I’ve ever had. I do wonder if either we’re going to see the ARM MacBooks have about the same lifetime as iPhones, or if iPhones will end up being supported for longer since they are architecturally very similar.
I expect the more modern Apple Silicon based ARM devices to have a longer support lifespan than older Macs.
