My impression about ML is that it shines where "intuition of a master" is needed. That is, for example, the mastery of a "technician painter" who has build an intuition of imitating Van Gogh painting can be achieved through AI.

Any intuitive skill that can be built through hard work and years of experience seems to be within the realms of what AI/ML can learn to do. Separating background from the subjects, guessing the 3D shape of an object from a 2D image etc. Anything that people can master through experience, including stuff like "sensing that there's something fishy but can't tell exactly what" kind of intuition.

I bet that there would be welding machines that can help an amateur to weld like a master by learning and imitating the way a master welder does its job.
