Indeed, the entire text of the Bible fits in a corner of my year-old box's
RAM, even at 32 bits per character.

Well, they still do -- fancy editors use fancy data structures, so that,
e.g., inserting characters at the start of the file doesn't cause a 50Mb
memmove each time.  Response time is still important, but I'd wager
relatively insensitive to basic character size (you need tricks that cut
factors of 1000s off potential worst cases to give the appearance of
instantaneous results; a factor of 2 or 4 is in the noise compared to what's
needed regardless).
