But self improvement doesn't require interacting with an outside environment (unless "improvement" means increasing computational resources, but the outside being simulated nullifies that). For example, a theorem prover designed to self improve can do so by writing a provably better theorem prover and then transferring control to (i.e., calling) it. Why bother with a simulated universe?

A simulated universe gives precise meaning to "actions" and "utility functions", as I explained sometime ago. It seems more elegant to give the agent a quined description of itself within the simulated universe, and a utility function over states of that same universe, instead of allowing only actions like "output a provably better version of myself and then call it".

From the FAI wikipedia page:

One example Yudkowsky provides is that of an AI initially designed to solve the Riemann hypothesis, which, upon being upgraded or upgrading itself with superhuman intelligence, tries to develop molecular nanotechnology because it wants to convert all matter in the Solar System into computing material to solve the problem, killing the humans who asked the question.

Cousin_it's approach may be enough to avoid that.
