I had been waiting for apple silicon with more than 32G of memory. It looks like that’s never going to happen.
You're jumping the gun a bit there. The only Apple Silicon MacsBooks released to date are the Air and the low-end (2 TB port) MacBook "Pro". The Intel models they replaced have never supported more than 16GB of RAM - a restriction which is also common of competing ultra-portable, low power laptops, and is partly a consequence of using LPDDR4 RAM, which has to be soldered in close to the CPU (no plug-in modules) and currently (I think) tops out at 8GB per chip.
When Apple replaces the higher-end MacBooks, particularly the 16", they're going to need an improved processor with more cores, a better GPU, more i/o bandwidth and support for more RAM. Currently, there's no reason to suppose that they won't deliver that: nobody is expecting those machines before this spring
at the earliest and Apple said the transition would take a couple of years. In the meantime, the higher-end Intel Macs are still available, and mostly got an update last year and...
if you are a "professional user" they're probably what you should be buying now.
I'm not saying that Apple are perfect, and there are plenty of good reasons why professional users might want to dump Apple, but "I can't wait any longer for Apple Silicon" only 3 months into the transition is not one of them.
Where I
do agree with you is that the idea of having a major, compatibility-breaking OS release every. freaking. year. is a stupid, marketing-driven strategy. There
is a reason for not having the OS cast in stone - getting rid of legacy stuff is a big part of what makes MacOS different from Windows, and things like dropping kexts
will be good for security - but it doesn't have to be bundled up with a lot of cosmetic change-for-change's sake in a massive, monolithic upgrade every third quarter, and while you can choose to stick with an OS for at least 3 years, the change gets forced on you as soon as you (or a colleague) has to buy a new Mac. However, Apple Silicon is a strange peg to hang that complaint on: it is one case where a major OS overhaul
is essential.
That said, go ask some Windows users about Windows updates sometime - the grass isn't greener on the other side of the fence, just a different shade of brown, and you
really have to jump through the hoops to avoid having Windows updates forced on you at inopportune moments.
