AB testing doesn't show many very different variants, but a few (usually 2) which are only slight variations of one another. So the AI would still need very narrow guidelines (aka. an existing design) to build the interfaces for testing, it couldn't try a lot of variations, and the process would be slow, as each new set of iterations has to be presented to testers/users and evaluated, before the next small batch can be prepared.
