Adam Gleave estimates AI existential risk at approximately 10% over the next few decades.

“I'm probably somewhere 10% existential risk the next few decades from AI and I think that we could probably get that down to something like 1% without any major research breakthroughs just iterating and refining what we already have and taking a sort of careful engineering approach to systems and having good safety cultures at companies and not like stopping AI or anything.”
