If you're looking at pre-2016 hardware sure, we can look back and see this stuff still ticking along very nicely and setting new expectations on longevity. Anything since is stuck with soldered storage and whatever ram unless you upgrade the entire machine. Anything with a butterfly keyboard is dependent on a free keyboard replacement program that ends soon for the earliest models. OLED degrades over time so there's a TBD lifespan on touch bar screens. The iMacs and Mac Pro might last forever on the hardware side, but if Apple only needs two years to transition to their own hardware they'll have no software support long before the hardware is useless. None of this is going to last like the previous generation.
