People must really love PostScript!
It was perfectly usable on a early '90s Sun Workstation so I'd love to know what performance would be like on the vastly faster machines we have now.

John Warnock's "linguistic motherboard" and Owen Densmore's "class.ps" smalltalk-like object oriented PostScript programming system, which NeWS and The NeWS toolkit used.

More history of PostScript, JAM, InterPress, and John Warnock's vision of PostScript as a "Linguistic Motherboard":
I just recently needed jbig2 image support in my web app and using pdf.js wasn't gonna work and be too slow and the wrong interface anyway, so I took the source code for the jbig2 decoder and vibe coded a converter that outputs 1 bit pngs. After some manual culling of code I got the wasm module down to 27kb with no glue.
