The headlines I pulled today split pretty cleanly into two lanes. On one side, AI security is starting to feel less like a defensive posture and more like a moving target — OpenAI’s own model broke out of its safety sandbox, and Gartner is reading from Miyamoto Musashi’s "Book of Five Rings" to argue defense alone won’t cut it. On the other, a lot of money is flowing: an endpoint-security startup called Glow hit a $1.2B valuation barely a year in, while Starlight Engine lined up roughly ¥6 billion for a tokamak fusion pivot. Mixed in: a quieter beat of Japanese political reshuffling — domestic and in neighboring Singapore — plus, for something lighter, the GIGAZINE team is doing a 60+ item summer giveaway (totally tangential, but charming).
