Go check out the resource usage. Yes, it involves virtualization, but the stripped down virtualized kernel uses very little resources. Getting that information is a bit complicated by the fact that it's difficult to see the difference between the virtualized kernel and it's applications in a way that's consistent with the host OS, but it's really in the dozens of megabytes range of overhead for something like docker on mac.
Just to check, I opened simultaneous projects in Logic Pro and Ableton Live, I have a Rust project open in VSCode (Electron), compiling Erlang again, I have Slack, Discord, Signal, and Hey running (all Electron apps), and I have Firefox open with Twitter, Hacker News, Facebook (a dozen tabs, just for good measure), Instagram, FBM, Techmeme, NYTimes, CNN, and MSNBC. This is a 15" 2018 MBP with a 6-core i7 and 16GB of RAM, and the CPU is working pretty hard but RAM usage is currently at just over 12GB.
I think we as programmers have lost sight of how a single gif in memory is about the same size as a whole docker container.
