While I agree that we want volition for AI to become useful and
interesting, I'm not sure it must be evolved. A sufficiently clever
programmer might be able to write an AI program from scratch, although
it might turn out that this is so tricky and inconvenient that
everybody in their right minds will evolve AI and then tweak it.

I think you make the mistake of thinking that we need to put all the
complexity in by hand, which would likely be infeasible. But you could
set up a basic set of world rules that encourage emergence, and then
let the world develop (e.g. let virtual plants go through a run of
simulated evolution, generating a synthetic ecology with fairly
complex structures no human has had the need to program).
Second, I don't see why you need to create a very complex virtual
world. It might turn out that "rather complex" worlds will do just as
well for creating basic AI. One might even have a succession of worlds
of increasing size and complexity, where the AI grows up until it
emerges in the real world.
