That's a code time dependency which is of least concern. That's like saying how can a company hire a developer, they are now having a dependency.
Code written will continue to run, you can use alternate LLM to further write code. Unless you are a pure vibe coder, you can still type the code. IF programmer stop learning how to write code, that's on them and not Claude's or antirez responsibility.
We are using best tool available to us, right now it is Claude Code, tomorrow it may be something from OpenAI, Meta or Deepseek.
