Ah -- brew is definitely not mature on the M1 Macs yet as I understand it.
I've been on the fence for a couple of months over this -- I want to grab an M1 Mac for R&D type stuff, but at the same time I want to wait until they release the 16" with a hopefully upgraded M1 of some sort.
You should probably get one anyway, it's incredibly life changing. You can always sell it on eBay after the 16" comes out, they hold on to their value pretty well.
