In less than a week, the council is already falling apart, a development that may jeopardize Google's chance of winning more military cloud-computing contracts.

On Saturday, Alessandro Acquisti, a behavioral economist and privacy researcher, said he won't be serving on the council. "While I'm devoted to research grappling with key ethical issues of fairness, rights and inclusion in AI, I don't believe this is the right forum for me to engage in this important work,'' Acquisti said on Twitter. He didn't respond to a request for comment.
