David Foster - Hardware, software and the speed of execution
Type of Spiritual Experience
I'm afraid I do not know which David Foster said this of the many David Fosters there are, but the quote was in a book on music, so there may be a connection there.
A description of the experience
A control system must have a fundamental tempo many times faster than the controlled process, since it has to anticipate every eventuality and possibility and it has to also have a reserve time for 'thinking'. This can only be so if the controlling software works in a quite different and faster time scale than the hardware – the faster the vibration the more the potential information content.
