First, let me say I much prefer discussing stuff like this here than on Reddit. They are so fussy in the Reddit Mac discussion area that I’ve never gotten a post past the moderator! And here I actually get replies. 
Anyway, time to upgrade my 7 year old MacBook Pro? But… even the Pro versions of the new Apple Silicon CPU computers apparently have only 2 Thunderbolt ports and a max of 16 GB RAM (which I have now). So not sure what the merit would be other than a larger SSD.
Any thoughts?
