Who Owns the Loop Where AI Does the Work? with Ksenia Se

In this episode of This Week in AI, host Ksenia Se, founder of Turing Post, took us through three stories that may look unrelated but all point to the same shift: AI is moving out of conversation and into the operational infrastructure where real work happens.Ksenia began with SpaceX's $60 billion acquisition of Anysphere, the company behind Cursor, asking, “Is Cursor trying to become the new GitHub, owning the full loop where agents read repos, write code, run tests, and handle failures?” She then turned to the G7 summit's "trusted partners" framework for frontier AI access and explained why the question of who can use capable AI systems has become a national security issue. Ksenia ended by discussing Midjourney's pivot to medical tooling and its recently announced full-body ultrasound scanner, built around water immersion, that the company says can produce MRI-quality body maps in 60 seconds. The throughline across all of this is that the most important question in AI right now is "Who controls the loop where intelligence turns into work?"
