Well, I'm 60 this year, and I have had macs since the early 90's. I have worked with all sorts of Macs since then, in work places, mainly daily newspapers (mostly as a night editor). I bought a Mac mini i7 Late 2012 in 2013 and immediately installed 16 GB RAM. I am now typing on an MBP i7 15" Mid 2014 (I'm staying with my girlfriend), and at home I have an MBP M4, both with 16 GB RAM. That has been the sweet spot for over a decade. 8 GB RAM has been too little all that time for serious computing with Mac OS X/macOS. I just don't understand why people are defending 8 GB RAM.
I don't think they're defending 8 gigs in 2025, but then, you can't buy a new a with 8Gb of Ram.
What is significant is that, for a lot of people, as you've said, RAM requirements have stayed pretty stable. 8 gigs of Ram in a Mac was absolutely fine for most tasks until and including Monterey - it wa sonly after that it became a problem.
Most with with a Mac are not editing 4K or 8K video, they'r not running LLMs at home and they're not gene sequencing.
I still have two Mackbook Airs, 2014 and 2015, with 8 Gb soldered on in both - they are still very capable "traveling" laptops. The issue with them isn;t the RA,, it issue is the screen quality.
For Monterey and below, no, I don't think 8Gb is too little RAM.
