An important thing to keep in mind is that 10% in which AI destroys humanity is a scenario in which the AI goes rogue and decides to destroy humanity of its own volition.
I think if we're being more realistic, there's a much larger chance that AI destroys humanity at the instruction of its masters. Once AI can automate enough industry, silently distribute IFFs among the Epstein class, then send out drones to kill any humans without.
