I think both are true. Claude Code was one man's experimental project, but it's an application of AI, not AI itself.

Anthropic is a large company, with thousands of employees, and seems to be 100% (maybe 200%) LLM and scale pilled. All the advances from one model generation to the next are the result of dozens of experiments first at small scale then at larger scale, all competing for the same "development compute" portion of their overall "development + inference" compute resource.

In this environment, even if there are researchers who have ideas not on the "LLM + scale is all you need" path that Dario seems hell bent on, there seems to be not much chance that these ideas can compete for resources and compute with the mainstream experiments that the company believes their future depends on.

Maybe an individual developer like Sutskever, engaged purely in research rather than manning a barely turnable oil tanker, can make a difference, but at a company like Anthropic it seems way less likely. Cherny's baby is 100% aligned with Anthropic's mission of selling LLM tokens. Someone else fighting the mission, trying to pivot Anthropic in a new better direction is not likely to have such luck.
