"This new book contains a series of predictions about the 21st century from thirty of today's great minds - including Noam Chomsky, Arthur C. Clarke, Richard Dawkins, Umberto Eco, J.K. Galbraith, Steven Pinker, and Peter Singer." "The predictions outline the discoveries and changes that the contributors expect to see happen, both inside and outside their own fields. Each prediction is preceded by a profile of the author, setting their work in context and explaining their theories or inventions."--Jacket.
