Is Machine Learning Driving AI?

Always thought ML was part of AI.   In Datanami: An interesting distinguishing point is made

" .... The authors quotes Jaime Carbonell, a professor of computer science at Carnegie Mellon University, as noting” “Machine learning essentially is the engine that is driving modern artificial intelligence.”

Machine learning “often deals with unbalanced data sets in which the ultimate focus of decision making is precisely the outlier cases,” that is, the extreme cases that contrast sharply with typical data and provide opportunities for the “most important learning opportunities.”

Ignoring the rare cases, or outliers, means “you cold miss everything [in a data set] that is interesting,” Carbonell asserted. .... "
