This is very interesting. You wouldn't normally hire an investigator to dig into a corporate shitshow. Firing of Sam Altman was a huge mess, but if there was a serious reason to do that (like, frauding the board), and that reason would be backed by investigation report, it'll suddenly make board actions much more justifiable. And it'll put Microsoft into a tough spot, because they hired Altman back without any considerations whatsoever...
People confabulate just like AI does. Just because the stories don’t add up doesn’t mean somebody deliberately lied.
