The Asahi developers have also stated that Apple tends to keep hardware peripheral interfaces stable across generations (they speculate that this is to keep things easy for their own OS dev teams), and that this has so far proven to be true for M2 (and several iPhone generations before that), and thus once support is available , it should stay relevant for some time.
Given this, it seems like MacBooks could easily end up becoming the laptop of choice for Linux developers in the years to come.
