Ken Kahn first became interested in AI programming by children in the 1970s. He published the paper ‘Three Interactions between AI and Education’ (Kahn, 1977) while he was a graduate student at the MIT AI Lab and a member of the Logo Group with Seymour Papert and Cynthia Solomon. In the 1980s he built tools based upon the logic programming language Prolog to enable children to parse and generate sentences. Later he designed and implemented ToonTalk, a programming language that has the look and feel of a video game. For the past five years, as a researcher at the University of Oxford, he has been building and testing a library of AI components in the Snap! programming language.
