Oh, I’m sure there are lots and lots of systems that can do computations as sophisticated as working out the digits of pi. We’ve got lots right here on Earth. But we don’t call them intelligent. Even though some of them seem to “have a mind of their own”—like the weather. But I also think there are probably lots of extraterrestrials out there of the kind you’re talking about—with lots of history, evolution stuff and so on.
