Claude Code is trivially an attempt to hobble the rest of the software business: the PID controller, the control vectors, the ever change loss surface, the bash and JSON jank at the foundations, the no one is this stupid context management, the some-data-critical-to proceed | tail -n 5, the sed editing, the speculative execution of partial frames.

OpenRouter and Opencode show you how behind it is, that bootstraps you off of them. They have issues too and Zen is starting to feel icky, but they let you speed run to the next thing.
