Understanding the US – China AI & Quantum Landscape

Not a scoreboard but a field guide: two very different systems building AI and quantum by different roads, bound together by a supply chain neither controls. Shayne Heffernan maps the landscape against the KXCO AI Sector Ontology. Artificial intelligence and quantum computing are usually reported as a two-horse race, a scoreboard on which the United States and China trade the lead each quarter. That framing is easy to write and mostly wrong. What is actually taking shape is something more interesting and more useful to understand: two very different systems, built on different assumptions about capital, openness and the role of the state, arriving at overlapping capabilities by very different roads — and increasingly dependent on one another through a shared supply chain neither fully controls. This is a field guide to that landscape, not a running tally of who is winning. To keep the picture honest, this analysis is mapped against the KXCO AI Sector Ontology — a live, independently verifiable graph of the AI sector's companies, models, capital flows and dependencies. The ontology is useful precisely because it resists the scoreboard instinct: it shows a sector that…
