It is very infrequent that the cover of Science evokes depressing thoughts. The 12 September issue's [cover][1] is one of them. It was exactly 35 years ago when, as a graduate student, I took a one-semester course in Artificial Intelligence. I had an excellent textbook: Problem-Solving Methods in Artificial Intelligence by Nils Nilsson. It was a fascinating subject; at the time, researchers earnestly felt that wonderful capabilities were just around the corner, if only we had somewhat more powerful computers. I did not pursue a career in Artificial Intelligence. I regretted that for a long time, but looking at this issue's cover story, I wonder if my regrets were misplaced. After 35 years, is reCAPTCHA the state of the art in Artificial Intelligence? What happened? If I had a time machine that allowed me to go back in time to 1973 to show today's Science cover story to the people working in Artificial Intelligence at that time, I wouldn't do it. Nobody would ever believe me. I find it hard to believe it myself that, in the 21st century, transcription of printed text still requires human intervention.
