It seems we just passed the 20th anniversary of the release of Emacs
21! Since then, I think a lot of assumptions about hardware have
changed or are changing: GPUs are now ubiquitous, hidpi is here to
stay, laptops have precision multitouch trackpads and touch displays,
the end of Dennard scaling and subsequent move towards parallel
processing for performance gains. I often wonder what emacs "core"
would look like if it were rewritten from scratch today with an
emphasis on performance. I imagine Firefox's transition of gecko to
rust components from servo over the last several years is probably a
good indication of what such a rewrite looks like for a complex
codebase.
