Is it just / ?
I kid. But really, besides “its all a file”, if you take away the gui, is the only difference the syntax ? How libraries interact? How disks are mounted ?
If we stripped all ms’s junk out and made windows open source, would we still prefer linux?
When you get to a very basic level, is one of them more efficiently coded?
It’s no longer maintained, right? So wouldn’t count.
It’s already been made perfect once. What updates would you make it divinely inspired code?
I wouldn’t update a thing. I would pick and choose the parts I like when I like them.
