Abstract
Since the fifties of the last century there have been debates about the so called "technological singularity", motivated by the predicted and later actual exponential growth of the speed and power of computers. Recently the interest of futurologists and philosophers shifts to the so called "intelligence singularity" which some of them predict to happen soon after human intelligence is surpassed by artificial intelligence.
This study critically analyzes certain assumptions behind the concept of intelligence singularity, in particular the idea of explosive growth of intelligence of machines with the ability of designing machines more intelligent than themselves.
