This is correct- my daily environment usually involves multiple VMs and a Docker Compose setup, either a JetBrains IDE or Visual Studio Code, Chrome with some reasonable number of tabs open, Slack, and a few utilities. To further illustrate the reason why this sounds insane, before I was at 32GB, I was at 8GB, and conserved RAM by running Linux with an extremely lean setup (i3 + st + Chrome.) Now I have plenty to spare, and I'm using a much more rich environment.

So yeah, it is a little more complicated than just "Slack needed 32GB" - in fact, and thankfully, even my whole stack fits comfortably. It's what I upgraded from that it didn't work well on.
