The same can be said if your developers don't know how to build applications:
- without using syntax highlighting ...
- without using autocomplete ...
- without using refactoring tools ...
- without using a debugger ...
Why do we not care about those? Because these are commodity features. LLMs are also a commodity now. Any company with a few GPUs and bandwidth can deploy the free DeepSeek or QwQ models and start competing with Anthropic/OpenAI. It may or may not be as good as Claude 4, but it won't be a catastrophe either.
