First off, it was 5, not 18. :)

Second, there's not much evidence that TJ Watson actually said it.

Third, given that IBM had already been shipping accounting units with limited
plugboard programmability (the model 405) for almost a decade at that point,
it's reasonable to conclude that TJ was intentionally and specifically talking
about high-end "if you have to ask you can't afford it" systems.  And if you
look at the Top500 list now, 65 years years later, it's still true - there's
always 2-5 boxes that are *way* out in front, then a cluster in spots 5-20 or
so, and then a *really* long tail on the way down to #500.
