also, this example is with a greenfield project where much of the use was in project setup. cool! LLMs are much worse at working with existing codebases, which is where the vast majority of software developers' time is spent.

still no evidence that they actually save developers time. the time saved from writing the code yourself is replaced with the time that you are writing detailed prompts + needing to painstakingly review and test what the LLM wrote.
