Another day of thinking about scenario 2 gave me a sci-fi idea: there’s nothing stopping us here in 2-world from constructing “ships” that would reliably survive in 3-world. (Remember that 3-world is right here, around us, we just don’t see it.) From our point of view the ship will self-destruct immediately upon launch, but the onboard computer will see a different picture: everything around it self-destructs and goes crazy, but the computer itself becomes awesomely powerful and can solve NP-complete problems in polynomial time. The idea is essentially identical to quantum suicide computing or reality editing. Of course, such a machine can never go back to our world.

Isn’t it a special case of what I discussed in last paragraph here (which you dismissed)?
I didn’t deny it was possible, but I did deny that we’d want an FAI to do it.
You could have linked to that comment so people who didn’t read that thread could see where the idea came from.
