I'm going to get 32 GB because:
-My 2019 16" had 32 GB and while it might have been overkill, I'm not going to "downgrade".
-The early reviews of M1 machines pointed out that they used a lot of RAM, and if the RAM was inadequate, the SSD was being used at a higher rate (or something like that, I don't remember, but it freaked me out).
-I want the highest graphics option, which presumably will require more RAM since it will be shared.
-I agree 16 GB feels old. My 2016 13" MBP had that and five years later, I feel it's time to move on. SSD storage keeps increasing, RAM in the iPhones has increased since then, time to get the next step up.
I'm just hoping that rumor that the 32-core GPU will require 64 GB of RAM is not true.
