I see tests as more of a test of the programmer's understanding of their project than anything. If you deeply understand the project requirements, API surface, failure modes, etc. you will write tests that enforce correct behaviour. If you don't really understand the project, your tests will likely not catch all regressions.

AI can write good test boilerplate, but it cannot understand your project for you. If you just tell it to write tests for some code, it will likely fail you. If you use it to scaffold out mocks or test data or boilerplate code for tests which you already know need to exist, it's fantastic.
