I can see a possible future where taste is automated. If you can effortlessly make 1000s of iterations then you can test it on real people 1000s of times. The ones that do better you keep.

Another possible future is that taste is not automated but its not part of the designer's job (if designers still exist). Instead some AI will generate 1000 of iterations and people will be employed to evaluate 100s of software UI each day for taste. These will be taste farms if you like. These people full time job will be saying yes or no.

Other possible futures also exist.
