Instead, only critical software makers have been granted access, providing them time to harden their systems. We quickly blew through our standard stages of processing big AI claims: shock, existential fear, hype, skepticism, criticism, and (finally) moving onto the next thing. I encouraged people to take a wait-and-see approach, as security capabilities are tailor-made for impressive demos. Finding exploits is a clearly defined, verifiable search problem.
