RAG Doesn't Cure Hallucination, It Relocates It

Retrieval-augmented generation was sold as the fix for AI hallucination. Five years of deployment show it just moves the failure from the model to an unaudited retrieval pipeline — and a wrong answer with a footnote is more dangerous than an obvious bluff.

Apple Is Running Out of Big Markets: Why the Next $120B Category Doesn’t Exist (Yet)

Apple stands at a pivotal moment. With nearly $400 billion in annual revenue, the company has outgrown most consumer markets on the planet. TVs, wearables, smart home devices, even VR and AI — none are big or profitable enough to meaningfully move Apple’s needle. As the search for the “next iPhone” continues, Apple faces a new reality: there are no existing markets left that can add $120B+ in new growth. The future will depend not on entering new industries, but on creating entirely new ones — and redefining how billions of people interact with technology.
