That's interesting, I must have missed this when I first learned of
Tegmark. Leibniz would say that all unnecessarily nonexistent programs
would exist, and that there are some that can become unnecessarily
nonexistant or become existing through various means, but does Tegmark
directly mean to say that all possible computations are platonically
eternal and already implemented?
