But I don't think they're suggesting getting rid of the entire executive team, or carte-blanche implementing whatever iCEO says to do. They're saying replace the most expensive position with some AI, and let the executive team debate that.
Seems like we could figure out a way to find accountability in that model by assigning it to whoever is best aligned with the decision - and could provide an interesting balance for the board to debate: Why did you decide to go against the machines recommendation?
