Is AI Not a Bubble? More Than 100 Trillion Won in Investment in AI Infrastructure Could Be Justified by the Success of Coding Agents

AI infrastructure spending is surging, with major players like Amazon, Microsoft, Google, Meta, Oracle, Anthropic, and OpenAI driving huge demand for data centers, chips, and power.

Simon Willison says coding agents such as Claude Code and OpenAI Codex show clear product-market fit, based on his own heavy usage.

He argues that at API-style pricing, his usage would be worth far more than a flat subscription, suggesting enterprise pricing could unlock major revenue.

If coding agents keep producing high-value business use, they could help justify the massive AI buildout that skeptics call a bubble.
