Docker is reasonably performant only on Linux. On macOS it's a fat slow VM that bogs down the whole machine (unless you make the VM even slower by giving it fewer CPU cores), has a horrendously slow network file system, and it's managed by a needy Electron app.

And don't forget that all new Macs are now ARM-based, so x86-based Docker images don't work.

My gripe with C is that everyone pretends it's portable, but only care about porting to one (their) platform. It's easy: just use pkg-config/docker/nix. Windows? macOS? Who cares!? Just run a Linux VM!
