People still believe in that notion of "beauty is subjective".

Beauty is objective, no, not just objective, it's so precise and mathematically defined that you can train a deep-neural-network to learn facial features from models' pics and make "hollywood filters" for apps like in faceapp and transform your face into a model-version of your face.

No, it wont replace your face with that of young Brad Pitt, it will subtly change the shape of your face and turn you into a model.

Just to add, machines can only crunch numbers, they are not capable of appreciating poetry or art. Also, a neural network with a hidden layer can learn "any" non-linear fuction with a back propagation algorithm (at least according to the theory).

May be that's why all "hot guys with cute personality" look so similar?

So there you go. Correct me if I am wrong.
