Same. My M1 Max only shows it age when building a few massive C++ projects, the M4 cuts down compile times to a quarter so I feel like I'm missing out there, but not enough to put down another$4k yet.

Compared to every Intel MBP I went through, where they would show their age after about 2-3 years, and every action/compile required more and more fans and throttling, the M1 is still a magical processor.
