As a counterpoint, I have a 2015 MacBook, a 2015 iMac, and a recent Apple Silicon MacBook. Of course I do Photoshop, Lightroom, Generative AI, etc. on the Apple Silicon system. But I basically don't care which system I browse the web with and, in fact, the iMac is my usual for video calls and a great deal of my web document creation and the like.
I suspect that people who have somewhat older Macs (obviously there's some limit) who find their web browsing intolerably slow probably have something else going on with either their install or their network.
I do some local image generation now and then (mostly using Photoshop). Are you happy now? My only point was that any CPU/GPU-intensive applications I run (and really most local applications) I do on my newish computer. But most stuff I run is in a browser.
The relatively little LLM use I do is in a browser and it doesn't matter which computer I'm doing it on.
