Take note: That you downvote people you disagree with (even when they have nearly half a century of experience) means you are not someone I'm terribly interested in engaging with even if I don't care about the downvotes themselves.
PS: My first Apple laptop was a PowerBook 170, connected to a Radio Shack bag phone via (USA) standard RJ11 jack. My first Mac laptop running Linux was a 17" PowerBook G4 running Yellow Dog Linux (whose legacy is "yup"). I've been writing software for Apple systems since the late 1970s (as well as my big systems and embedded background) and I'm far younger than 60. Bye.
I'm not sure what you are on about about downvoting. I didn't downvote you. In fact I have 3 upvotes. Maybe the downvotes came from those same people. Maybe that is because your stance is actually not that great.
I probably should have written something simple like "m1..m4 will age like Chromebooks" but I have a lot of simultaneous tasks going on.
BTW, thanks for not downvoting and I apologize for accusing you of doing it. Let's chalk it up to Apple employees (who, from my perspective, are a type of lost souls). Never be afraid to say what you need to say!
