Gary Drescher once reminded me that von Neumann may have already suffered neurological damage from metastatic cancer at that point, so this lower bound may not be as high as you think (unless that's what you were alluding to by "true reasons").
Von Neumann had been a practicing Catholic earlier in life, so it's not that strange that he would return to Catholicism near the end. By "true reasons" I didn't mean brain damage, though thanks for bringing up that possibility. He was still transhumanly intelligent up until the end, but maybe not quite as transhumanly intelligent. But I guess I just meant that Pascal's wager surely wasn't his only consideration.
Are there any essays anywhere that go in depth about scenarios where AIs become somewhat recursive/general in that they can write functioning code to solve diverse problems, but the AI reflection problem remains unsolved and thus limits the depth of recursion attainable by the AIs? Let's provisionally call such general but reflection-limited AIs semi-general AIs, or SGAIs. SGAIs might be of roughly smart-animal-level intelligence, e.g. have rudimentary communication/negotiation abilities and some level of ability to formulate narrowish plans of the sort that don't leave them susceptible to Pascalian self-destruction or wireheading or the like.
At first blush, this scenario strikes me as Bad; AIs could take over all computers connected to the internet, totally messing stuff up as their goals/subgoals mutate and adapt to circumvent wireheading selection pressures, without being able to reach general intelligence. AIs might or might not cooperate with humans in such a scenario. I imagine any detailed existing literature on this subject would focus on computer security and intelligent computer "viruses"; does such literature exist, anywhere?
I have various questions about this scenario, including:
