CEO of OpenAI since 2019. Being the leader of one of the three most major players in the AI race, his decision making could arguably affect directly the future of the whole humanity.
If OpenAI succeeds into summoning the first AGI to the world, he could be one of the most important people that have ever lived.
He has many times expressed concerns about existential risk and yet he has been acting in a completely inconsistent way.
Frequently accused for being disingenuous, machiavellian and manipulative, one of his most dramatic recent moments included a failed attempt for OpenAI board of directors to oust him, (exactly because they concluded they could not trust him) a decision he managed to overturn and eventually use to establish a new board of loyalists, consolidating more power and making OpenAI more “Closed-AI” than ever.
