Maybe robot professors are not a bad idea?

Robot Professors?  Couldn't most lectures be taught in this manner?  Should professors (law included) focus their time on more office hours, for one on one interaction with students, and grading exams (although this software even allows that be done by computer)?  Would that allow universities and colleges to hire less professors to teach more students, allowing professors to teach more productively and making the cost of education less expensive?
