> You can enable virtually free test driven development. Write the test names down and let the LLM implement them for you. You save 50% of your time and you get to go to town on implementation and or optimizations.

That's assuming that it writes good tests, and that you don't care to take the time to verify the tests it wrote, no?

I do find LLMs useful for scaffolding this stuff, but yeah, good test writing still seems to require a lot of hand-holding. I don't mind. I'm happy with my tests and they get written faster. Hand-holding and verifying is still faster than how I used to do it, and the LLMs admittedly capture more cases than I did without them. They will try to create test cases that make no sense too, but it's worth having to delete if it means it also comes up with test cases that I didn't.
