The first consumer processors with multiple cores came out around 2005. Before there were multiple cores in consumer machines, there was no reason to implement concurrency in a way that would scale to multiple cores.
- TeMPOraL 5y agoNot to mention, back when the Emacs we know today was created, there weren't many GUI platforms available in the first place. First public release of GNU Emacs - the one with Emacs Lisp - was in 1985, so the Emacs we know is ~3 years older than X11. Emacs added GUI support in 1986[0] - before X11 was a thing (though X itself existed since 1984). Emacs started as a terminal app, the GUI was added as an afterthought, by pretending it's a TTY. The concept of a "UI thread" wasn't on Stallman's mind back then. It continued to evolve from there; fast forward 35 years, and now we're living with a GUI program that still thinks it's writing to a teletype[1]. -- [0] - https://stackoverflow.com/questions/10084842/first-gui-version-of-emacs https://stackoverflow.com/questions/10084842/first-gui-versi...

- diragon 5y agoIsn't the issue more concurrency than parallelism, though? Concurrency works just fine with a single core thanks to kernel-level juggling. They would've been wildly forward-looking if they had figured this out 35 years ago though.
