Blog #0194: The Time Cost of How Is Zero Agentic coding pushes the implementation cost of software towards zero. The value shifts from how to build something towards why and what. But this is just the latest rung on a very old ladder.

AI is neither the cure for all things nor a hoax. Just another tool (a powerful one).

I liked @matthewsinclair.com 's argument that it is one step further towards declarative programming. Like TF but for software.
