I'm finding the defaults of Ghostty super fun😎

Ken Thompson and Doug McIlroy are still around. I can't seem to find an interview about such things, as interviewers tend to focus on the early days of UNIX and suchlike; but they do both have public email addresses, so we could always ask.

Systemd

I don't, because I don't have all the answers. Nowhere near. When given any fantasy situation ("how would X from Y feel about A from B?"), there are good answers with basis in what the people actually said, and there are feelings about humanity in general. Guesses, if you will.

Morbidly curious, but also afraid to see an example of the conversation veering that far off topic.

These are good points to a degree, but how do you explain Plan 9? Isn't Plan 9 essentially historical proof of their principles rather than adapting to necessity? I'm not saying they wouldn't be impressed or enjoy taking liberties in tons of conveniences, but don't you think this would later appeal to their original inspirations and ideals? A part of me thinks that a few would eventually think, "These sharper tools and greater resources deserve more elegance/simplicity and composition.

I almost avoided namedropping systemd because it seems to now essentially have it's own Godwin's law in the niche software circles :P

This kinda feels like bait for systemd venting.

I honestly don't think they would.

You're talking about taking people from decades past, showing them a new computer and wondering what they'd fix. I think they'd be more amazed with how far their software has come.

You might be thinking that modern operating systems are bloated and out of control. I think their founders would be impressed that they no longer have to work that hard to make the software work on modern hardware.

Apple guys say modern Macs would make Steve Jobs roll over in his grave. I think he'd be impressed by Liquid Glass and the very fact that we can do it.
