If that’s not “the rest of the owl” I don’t know what is.
Let’s swap out superintelligence for something more tangible. Say, a financial crash due to systemic instability. How would you insure against such a thing? I see a few problems, which are even more of an issue for AI.
1. The premium one should pay depends on the expected risk, which is damage from the event divided by the chance of event occurring. However, quantifying the numerator is basically impossible. If you bring down the US financial system, no insurance company can cover that risk. With AI, damage might be destruction of all of humanity, if we believe the doomers.
2. Similarly, the denominator is basically impossible to quantify. What is the chance of an event which has never happened before? In fact, having “insurance” against such a thing will likely create a moral hazard, causing companies to take even bigger risks.
3. On a related point, trying to frame existential losses in financial terms doesn’t make sense. This is like trying to take out an insurance policy that will protect you from Russian roulette. No sum of cash can correct that kind of damage.
