When’s the last time an ice deliveryman visited your home? Have you ever talked to a telephone switchboard operator? Thanks to new technologies, these once-common occupations passed into history many years ago now. Bank tellers and travel agents are not completely obsolete, but substantially fewer people are employed in these lines of work than in the past for similar reasons.
Will new developments in Internet-based communications technology do similar things to college professors? Perhaps people like me will face the same trouble finding employment that newspaper reporters or piano tuners face nowadays. Or perhaps MOOCs will eliminate the need for professors almost entirely, allowing students to flock to courses offered by a smattering of "super-professors" while computers, graduate students and adjuncts do all the grading that once occupied so much of an analog instructor’s time.
