Been writing code for 15 years. Now, I spent all my time defining specs, creating tests, and validating Claude’s/ChatGPT code (not reviewing, but validating with tests). The speed of development and quality of code is just amazing.

Doesn’t mean I don’t use existing code. In fact, LLMs tend to be great at finding existing libraries and reviewing potential sources should always be part of your prompt. Writing code from scratch is good for prototyping, but existing libraries tend to be much more robust and battle tested
