Try running mini-unix on floppies (we did) and you'll know why there's still
a problem.  Mini-unix generally ran on machine with no MMUs, yes, but those
machines generally had relatively fast hard disks.  So mini-unix kept one
program in memory at a time and swapped every time it did a context switch.
Even with good hard disks, mini-unix performance didn't sparkle.

Considered as a fixed-wing aircraft (which it isn't) a bee can't fly; there's
nothing wrong with that proof except the initial assumption.  Same situation.
