    Imagine a hologram of a computer that computes at the speed of light. Is this the shape of the future?

    Since these circuits would only be in partial use, and electricity moves fast anyways, would we really notice a significant difference. So often we have subroutines making background calculations we are fast enough already. I suppose if I said why would we need faster computers someone 100 years from now might think that is simply hilarious.

    How fast does electricity move through our computers now?

    About one meter per second, but the signal is MUCH faster
