the ARM and Intel Macs are very different animals at this point - even if the naming and computer case happens to be the same.
...but, then, so are the 2-port 13" MacBook Pro and the 16" MBP. Or the white 2009 MacBook and the 2016 12" MacBook. Or the 2012, 2013 and 2019 Mac Pros. In fact, the cases aren't even the same...
Partly, I'm thinking of practicality rather than principle: trying to stop M1 Air users posting to the Intel Air forum, and vice versa, would just be an endless losing battle.
Also, while there are many processor-specific issues, there are many more that are general to MacOS and the physical design of machines. Having more and more forums just scatters these more widely and reduces the number of people who will see them and maybe know the answer.
And besides, the main reason I brought it up is that there already is a dedicated 'ARM" Mac area, and there already is a dedicated 'PPC' Mac area.
I'm not against an "Intel Macs" forum
per se but I don't think its time has come just yet. Maybe when "Intel" has become a legacy issue (like PPC).
The "Apple Silicon Macs" forum on the other hand is important for all the "Does
x run on M1", "How fast is your M1 and
x", "What will M2 be like" and "I'm swapping my 28 core 2019 Mac Pro with 1.5TB RAM for an M1 - should I spend an extra $200 to get 16GB RAM?
" threads that don't need sorting by model.
Incidentally - here's a snippet of the MacRumors forum page from August 2006, a year after the PPC-to-Intel transition was announced,
7 months after the release of the Intel MacBook Pro and a few weeks after the release of the Mac Pro which "completed" the transition:

...so by discussing this now, a month or so after the very first M1 launch, we're kinda ahead of the game!
