"Ahead of OpenAI CEO Sam Altman's four days in exile, several staff researchers sent the board of directors a letter warning of a powerful artificial intelligence discovery that they said could threaten humanity, two people familiar with the matter told Reuters."

Will it be confirmed by OpenAI employee or the board member that there was a letter from worried employees?

Resolution criterium: As a confirmation. I mean an article in the press citing a named employee, board member, or ex-board member, or a tweet/post/etc. from a non-pseudonymous OpenAI employee, board member, or ex-board member.
