Anthropic is making the argument that the ratio of human to useful code committed is decreasing rapidly over time, while anthropic continues to meet milestones and beat competitors and ship product: real world indicators that prevent their engineers from committing broken slop code, which means the human-to-code ratio is a real improvement, and looked at on the whole, does irrefutably offer evidence of a feedback loop system where the AI is self-improving, but slowly draining humans from its learn-improve feedback loop, while still meeting/exceeding all objecting real world metrics for successful improvement. It's a thoughtful way of framing self improvement, and yeah partly marketing hype, but also not wrong. It can be an observation that makes them look good, and be correct, two things can be true.
