I am not willing the entertain the idea "more RAM is no longer possible nor necessary", either. Software keeps creeping up as usual (MS Teams _by itself_ uses >2GB, and I have already complained dearly -- Teams is basically a glorified IRC client!). And next year if not this year already it's highly likely my phone will have 16GB of RAM. My phone! On my pocket!
It's just ridiculous that a $1200 laptop has 8 GB, and it is just unbelievable it maxes out at 16GB. Looks designed to be thrown away next year.
