I got an MBP M1 with 32gb of RAM. It'll probably be another 2-3 years or longer before I feel the pressure to upgrade if not longer. I've even started gaming (something I dropped nearly 20 years ago when I switched to mac) again due to Geforce Now, I just don't see the reason.

Frankly though, if the mac mini was a slightly lower price point I'd definitely create my own mac mini cluster for my AI home lab.
