For some time, I¡¯ve been collecting news stories about robots and jobs. By robots, I mean almost any automated process that substitutes machines for people. Here are some examples:

? The restaurant chain Chili¡¯s installed 45,000 computer tablets in its U.S. locations, says The Washington Post. The tablets enable customers to pay their bills, play games and place some orders.

One hotel is introducing a robot bellhop that delivers items to guests¡¯ rooms, reports The New York Times. The same story mentions automated golf caddies. Another Times story reports that the German firm Daimler has demonstrated a self-driving truck.
