Some ideas. - VMs for testing eat up memory fast. - A deep disk IO cache dramatically speeds up some workloads, even if processes aren't allocating the memory themselves. - Running a bunch of microservices locally (we have a webpack-based app that eats 16GiB easy - yes, yes... we're working on it). I think 64 is a bit extreme these days for a personal computer if you're not running a stack of VMs. Servers are a different story, of course.
