I don't think anyone should upgrade if they're happy, but I also think faster chips do have real-world benefits that tend not to be appreciated by people who aren't valuing their time enough. I replaced my M1 MBP with an M4 earlier this year, and it's had a couple real-world benefits:
- builds are noticeably faster on later chips as multicore performance has increased a lot. When I replaced my M1 MBP with an M4, builds in both Xcode, cargo and LaTeX (I'll switch to Typst one of these days, but haven't yet) took about 60% of the time they had previously. That adds up to real productivity gains
- when running e.g. qwen3 on LM Studio, I was getting 3-5 tok/s on the M1 and 10-15 on the M4, which to me at least crosses the fuzzy barrier between "interesting toy to tinker with sometimes" and "can actually use for real work"
