Yeah, statistical models just give you the most probable result (in terms of the data we train it on), so if you are a creative person, you probably won't find it useful.
Hmm, a model could also give you multiple very different designs to help you see more possibilities
Sounds like it would be ideal for situations where you want the layout itself to be as neutral and out-of-the-way as possible, since these are judgement biased by normalisation.
