I get the historical interest, but in today's world, is there any
advantage to ksh over bash? I get that lots of scripts are run
with /bin/sh and it is nice when that is fast, but aren't the cpus

Ubuntu chose it as the default shell for sysvinit startup scripts in
2006 (from which it spread to BSD) precisely because it was much faster
than bash. It's also smaller: bash is a memory hog.
it seems bash4 have solved the performance penalty :
