Holden might have agreed to have Helen replace him. She used to work at Open Phil, too, so Holden probably knows her well enough. Open Phil bought a board seat, and it’s not weird for them to fill it as they see fit, without having it reserved only for a specific individual.
That’s pretty wild, especially considering getting Holden on the board was a major condition of OpenPhilanthropy’s $30,000,000 grant: https://www.openphilanthropy.org/focus/global-catastrophic-risks/potential-risks-advanced-artificial-intelligence/openai-general-support#Details_on_Open_Philanthropy8217s_role
Thought it also says the grant was for 3 years, so maybe it shouldn’t be surprising that his board seat only lasted that long.
