I think you misunderstand me, in multiple ways.
1. I'm typing on a Mac. It's an i7 with Monterey. I have been using Macs since System 6 on a 68000 in 1988.
2. Mac OS X is a UNIX. Not a figure of speech: it is registered and conformant.

As such, Mac OS X contains software baggage that is over a decade older than Classic MacOS, released 1984.
It keeps more than you'd think.
3. Linux keeps more than you'd think, too. I can and do run WordPerfect 8 for Linux on Ubuntu 22.04, alongside MS Word 2003.
I wrote about how to get it:

4. On my Win11 box, I have Freecell Solitaire extracted from Win32S for Windows 3.1, released 30Y ago.
I don't need this level of continuity. I enjoy it. I still have machines that can boot into DOS and I have DOS apps I still use. But that is also fine in a VM.
But 30 years after NT, 54 years after Unix, I want all that legacy stuff gone.
I want legacy nonsense like "disk drives" and "files" gone.
I want an OS and apps in a type-safe native language, not some BS memory-managed VM. I have multicore 64-bit machines with gigs of RAM and these days I could fit terabytes of nonvolatile memory straight onto their memory bus. I want a transparent object store in persistent memory, like a modern multitasking Apple Newton that can handle live video and surround audio, that understands my voice and my tone and my gaze and can read my intentions and show me the results in VR.
I gave a FOSDEM talk about this. You might enjoy it.
