It kind of is?

Why would you not want your development environment to be as close to your deployment environment as possible? Even MacOS bash commands have hiccups every so often. In my experience working with Linux developers, they seem to know the internals of the servers much better and can optimize/debug prod fast - and this understanding is only compounded with LLMs.

I'm sure many developers would be equally talented at debugging such issues if we deployed on Windows or MacOS, but virtually no one does that.

I do other things on my computer apart from bash.

Docker was designed for Linux, and on Windows you have to run a VM just to let Docker function.
