I work with AI models all day every day, keep up with everything, love frontier tech, I love and breathe LLMs. And I, like OP, haven't seen the need to upgrade from the M1 MBP because it runs the small 1-7B models just fine, and anything bigger I want on some GPU instance anyway, or I want a frontier model which wouldn't run on the newest and biggest MBP. So it's not just us Boomers hating on new stuff, the M series MacBooks are just really good.
