I really hope our Government seeks out all these terrorists and Iran boosters on Hacker News who work in high tech. It’s a supply chain risk and none of them should be working.

And also--before Linux--SCO Xenix and then SCO Unix. It was finally possible to run a real Unix on a desktop or home PC. A real game changer. I paid big $$$ (for me at the time) to get SCO Xenix for my 386 so I could have my own Unix system.
For that matter, the "second" version of UNIX ran on a PDP-11/20 with no memory protection or MMU, and there were a few versions after intended to run on similar hardware (LSX, MINI-UNIX).
The PDP-11's MMU option was closer to the 8088's segmentation model I think, but I've never coded either, so dunno really. It does seem like it was possible to port "PDP-11 UNIX" to a lot more platforms than would get "VMUNIX".
The "Maker" movement and "vibe coding" have changed the way I do things. I 3D print several things a month, and now I make PC boards with KiCad, etc. It's an incremental change, but a change nonetheless
