What If Everyone Had a Personal AI Concierge?

Old MIT friends talk about AI Optimism. Beginning with the AI-assisted discovery of serious PHP vulnerabilities, we explore the escalating contest between digital attackers and defenders, the hidden data economy that leaves consumers exposed, and a provocative alternative to advertising: a personal, open-source AI concierge that works for you rather than the highest bidder. That leads us into harder questions about who pays for AI, whether superintelligence would actually improve human life, why power never seems to satisfy us, and whether new technology ever changes the underlying moral choice.
