Not running any LLMs, but I do a lot of mathematical modelling, and my 32 GB RAM, M1 Pro MacBook is compiling code and crunching numbers like an absolute champ! After about a year, most of my colleagues ditched their old laptops for a MacBook themselves after just noticing that my machine out-performed theirs every day, and that it saved me a bunch of time day-to-day.
Of course, be a bit careful when buying one: Apple cranks up the price like hell if you start specing out the machine a lot. Especially for RAM.
Which is a comparison that makes complete sense. When you say that someone is leading the way, you are clearly referring to them being at the forefront at the time when they were leading the way. Any system that was a trail blazer 100+ years ago should be outdated by now, unless progress stopped or went backwards in the meantime.
