This is just the start, just wait until most LLM can outperform junior devs on the quality of generated code.
Friends and I have all been working to experiment with these sorts of things locally, to reduce the cost to basically zero.
I am sure we can guess what 1-3 years from now starts to look like, as technical project managers and sr devs are able to harness many of these tools (see langchain) and just write english unit tests.
