I would, instead, phrase that as:
"You just can't educated everyone ... instantly."
It really isn't that surprising that a lot of people believe that a
kernel custom to their hardware is more efficient, that software
compiled with slightly difference compiler flags beats generic options,
or that you have to have a -smp or -up kernel.
Under Linux, for many years, that /was/ the case. Not as much as people
believed, perhaps, but the runtime selection of memory copy algorithms
and similar behavioural changes were actually relatively recent.
So, in a few years there will be hordes of people who will never believe
that you could want an SMP or UP kernel alone -- simply because they
have never seen one. ;)
