I disagree with the grandparent too, but still would argue that an OS's goal is to allow its users to manage their applications and work processes rather than their computer.

It's a hard question to figure out what's the proper level of abstraction for this is. And while I strongly resisted it originally, I am becoming more open to the argument that many people don't need to "know" what a file is, to benefit from their computers - that as long as they can "save" their work, and "send" it from one app to another, they'd be able to get all the productivity that they are looking for.

There’s a big difference between working on a computer and working with a computer.

The people doing the former use computers for ‘real work’. They are using a computer as an end in itself, care about operating systems and have strong opinions about systemd. The people doing the latter couldn’t give two shits about any of that and just want to get their presentation finished on time.

Problem is, both sets of people have to use the same machines. It’s also why software like GIMP will never become widely adopted in professional environments because it’s designed for a completely different userbase.
