No, you shouldn’t. When someone sounds smart, that means they are an effective communicator and have good media presence. Those are valuable skills but don’t indicate whether the underlying ideas are accurate.
Eliezer is filling the traditional doomsday prophet archetype, of which there have been thousands in history. That doesn’t mean he’s wrong, but should immediately raise questions.
A deeper analysis of his ideas shows there are fundamental problems in his reasoning.
First, He’s been consistently wrong about the future development and results in AI research so his understanding of AI is proven to be superficial.
Second, His doomsday scenarios are based on a fundamental fallacy; that a GAI smarter than humans would be insanely stupid, unable to self reflect or solve moral quandaries. That’s not to say AI cannot be dangerous, but the types of doomsday scenarios he presents are unlikely. For instance because of acausal trade, Rokos Basilisk is a serious risk that should be treated properly, but Elizer denies it.
