Everyone who profited from AI boom has upgraded their macbooks already. The rest can go back to putting fries in the bag.
My work machine went from an M1 with 32GB to an M4 with 24GB and it definitely wasn't worth the time to upgrade.
I went from an m1 MacBook to m5 earlier this year. It was almost too smooth - I just felt like I had the same computer and not a new one. Which in a way was disappointing.
