My apologies. Was thinking the interview was recent. Thanks for your reply and clearing that up! Hope you do more quiz shows, they're fun and informative!
Interview was recent :) But in the interview he was talking about considering it while he was CEO, but he's not longer CEO of those companies. Sorry for any confusion!
