Early Attempts to Replace Teachers with Games

The current push to bring digital games into school is, strictly speaking, not the first, nor even the second time that educators have pushed for individualized instruction via machines. But it is decidedly the most nuanced, humanistic, and thoughtful. The first actually took place in the 1950s and early 1960s, when a small group of educational psychologists proposed doing away with teachers altogether and replacing them with self-paced, preprogrammed instruction on so-called "teaching machin...

 Prescience of Genetic Engineering

As a matter of fact it was not until 1940 that Selkovski invented the purple alga Porpbyrococcus fixator which was to have so great an effect on the world's history. . . . Porpbyrococcus is an enormously efficient nitrogen-fixer and will grow in almost any climate where there are water and traces of potash and phosphates in the soil, obtaining its nitrogen from the air. It has about the effect in four days that a crop of vetches would have had in a year. . . . The enormous fall in food prices...

 "Susicion of Authority" is Also Propaganda

While individuals get our empathy and sympathy, institutions seldom do. The "we're in this together" spirit of films from the 1930s, 1940s and 1950s later gave way to a reflex shared by left and right, that villainy is associated with organization. Even when they aren't portrayed as evil, bureaucrats are stupid and public officials short-sighted. Only the clever bravado of a solitary hero (or at most a small team) will make a difference in resolving the grand crisis at hand. This rule of con...

 Does the Future Need Us?

While we now know that Turing was too optimistic on the timeline, AI's inexorable progress over the past 50 years suggests that Herbert Simon was right when he wrote in 1956 "machines will be capable ... of doing any work a man can do." I do not expect this to happen in the very near future, but I do believe that by 2045 machines will be able to do if not any work that humans can do, then a very significant fraction of the work that humans can do. Bill Joy's question deserves therefore not to...
