Thanks to Turing completeness, there might be many possible worlds whose basic physics are much simpler than ours, but that can still support evolution and complex computations. Why aren't we in such a world? Some possible answers:

1) Luck

2) Our world has simple physics, but we haven't figured it out

3) Anthropic probabilities aren't weighted by simplicity

4) Evolution requires complex physics

5) Conscious observers require complex physics

Anything else? Any guesses which one is right?

My guess is #2.
