People didn't write tests not because it was boring, but because they didn't have time to do it because implementation is more important. That problem didn't go away - it's just instead of not having time to do tests, now we don't have time to review whether the AI wrote tests that make sense. And most of the time it doesn't. They're running the code but not asserting anything. Or they're asserting test inputs instead of implementation outputs. Or outright swallowing errors to make tests pass.

Having such tests is, in fact, worse than not having tests at all. Non-existent tests are just as useful as bad tests, and are much cheaper to maintain.
