ERST

I have just invented a new acronym, ERST.
It stands for Electronically Recorded, Stored and Transmitted and I used it first when describing my latest version of the Melba Opera House, because it neen not be the biggest, best and most iconic Opera House, but it must ERST ready.
How do people call these things now?  Do we even have a vocabulary specifically for the virtual world that eventually people will inhabit as much or more than the so called "real world". Perhaps I am one of the few who has explored living in our world as if it had another dimension.  Mathematicians must all do it, because so much of mathematics accpet that real numbers are only a subset of numbers.  To calculate electronics that has our of phase oscilating electrical currents, it is necessary to use formulae that include complex numbers but the final result always turns out to be an expression with only real numbers, and this holds, I believe, for many systems, including Economics, so that the Complex world of ours with an extra dimension actually does have some ontological validity because it is necessary to explain or calculate what does exist.
My world is so different from that of most people.  I measure and count exponentially instead of linearly.  How long will it take mankind to catch up with that one?  I live in a world with an extra dimension, which is about a scifi as Dr who's extra heart, though of course physically possible against the biologically impossible Dr Who, the alien who is humanoid apart from his heart and phenominal intelligence.
