The economics of large language models—massive training costs, data advantages, and compute-intensive inference—create structural barriers that make it difficult for new competitors to emerge, though not impossible. Noah Smith's shift from bubble skepticism to acceptance of inevitability reflects analyst consensus that the question isn't whether concentration will happen, but whether antitrust or regulatory intervention can prevent it. Market forces alone appear insufficient to sustain meaningful competition once a few players achieve scale. The stakes turn on whether governments will tolerate a handful of private entities controlling infrastructure that increasingly mediates language, knowledge, and decision-making.
