R&D feedback loops in the Hanson–Yudkowsky AI debate

A commenter recounts Hanson's expectation that brain emulations would precede hand-coded AI and shift the economy to a faster growth rate. They argue Shulman showed how emulations could earn money, acquire hardware and speed up research, creating a feedback loop Hanson had not addressed. In the commenter's view, today's AI development looks more like that broader R&D process than the single self-improving mind they associate with Yudkowsky's account.
