you can trust the tests that you have written, but what about the tests that you didn't write? can you be sure that your testsuite is complete? when i do test driven development, all the thinking goes into the tests, and the actual code writes itself. LLMs hardly help make that any faster. having a complete testsuite may make it easier to use LLMs for refactoring, and adding features, but then you still have to write he tests for the new functionality.
