All true, but in the possible universe of things that could be wrong with an operating system, that's not that bad.

Instead, we would have to adopt a picture in which there is an ensemble of all possible universes with some probability distribution.

What happens to free will, to morality, if any and every universe possible actually comes to pass?

Freeman Dyson once remarked to me, about these issues, that he felt the best possible universe was one of constant challenge.

Almost all of the other possible universes, they say, are inhospitable.

And who was to say that, somewhere in the millions of other possible universes, it might not have worked?

Only a minuscule fraction of all possible universes can end up harmonious.

And even if they did, the possible universe of still-unused passcodes is still bigger than 15 million.

I imagine the possible universes arrayed around me in a kind of probability space.

I wondered if there were anything in the infinitude of possible universes that this craft could not do.
