I can’t imagine an organization where this wouldn’t have come up on some roadmap or prioritization meeting, etc. How could leadership not know what the org is working on?! They’re not that big.
Board is not exactly leadership. They meet infrequently and get updates directly from management, they don't go around asking employees what they're working on
Going into detail in a talk and discussing AGI may have provided crucial context that wasn't obvious from a PowerPoint bullet point, which is all the board may have seen earlier.
