Where does the article mention Claude Design? It seems to me the author is using LLMs as a tool for iteration, given he is a designer.

Also, you're mentioning a lot of unrelated tech. DPO, PPO, actor-critic, visual self-eval loops, Anthropic's "vertical product development stack" may be interesting, but they are mostly orthogonal. The article's point is simply that a designer can now turn design proposals into working prototypes faster than with Figma.

Also, you mention what seems to be a random product bug about disconnect and reconnect that doesn't have anything to do with this workflow. It seems to me that you're post-rationalising some insights that are not really there.

Good to think things through and in public, not discouraging it. I hope this reads as constructive.
