I enjoyed your interview with Stephen Grand, creator of nornssome of the most sophisticated artificial life around (1 April, p 42). However, I found his bald statement that artificial intelligence has failed because Alan Turing's predictions about it have not come to pass a little glib.
Grand proposes the use of genetic algorithms and a biological approach to solving the AI problemthe very same things which Turing himself proposed way back in the 1940s. Turing discussed "genetical" searches and unusual neural network architectures, and carried out some of the first work in a field which has since become known as morphogenesis.
For a small example of functional Turing nets (to our knowledge the world's first) see http://home.clear.net.nz/pages/cw/unorganized.htm.
The development of the programmable digital computer based on Turing's designs so eclipsed these ideas that they have been more or less forgotten. If Turing hadn't died at the age of 42, ...
