In computing, invariants are ephemeral.
The best architecture is the one that disappears, that is not noticed.
The most important computer is the one that rages in our skulls and ever seeks that satisfactory external emulator. The standarization of real computers would be a disaster - and so it probably won't happen.
It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.
