You could say the same thing about digital computers old and new. For example, for this (awesome) article http://horningtales.blogspot.com/2006/07/bit-serial-arithmet... describing an ancient bit-serial drum-memory computer, the author coins the acronym "AIGSA" to mean "as in grade school arithmetic".

But that just shows that we understand grade school multiplication. It doesn't mean that we know how best other people learn it.
