My M2 has an IDE and a couple active Firefox tabs open and I'm sitting at 30GB RAM usage, with about 5GB more on swap. It's a 32GB machine and I'm constantly opening Activity Monitor to kill Firefox tabs whose memory usage just seems to grow unbounded over time.
Software shouldn't be written this way. I shouldn't have to disable mds-store because it likes to take up 2-3 cores at full throttle when I'm on 10% remaining battery. But it is, and 32GB isn't enough for me to even have a basic computing experience anymore, it seems.
