"I highly recommend this book" --Bill Gates

"Nick Bostrom makes a persuasive case that the future impact of AI is perhaps the most important issue the human race has ever faced. Instead of passively drifting, we need to steer a course. Superintelligence charts the submerged rocks of the future with unprecedented detail. It marks the beginning of a new era." --Stuart Russell, Professor of Computer Science, University of California, Berkley

"Those disposed to dismiss an 'AI takeover' as science fiction may think again after reading this original and well-argued book." --Martin Rees, Past President, Royal Society

"This superb analysis by one of the world's clearest thinkers tackles one of humanity's greatest challenges: if future superhuman artificial intelligence becomes the biggest event in human history, then how can we ensure that it doesn't become the last?" --Professor Max Tegmark, MIT

"Terribly important ... groundbreaking... extraordinary sagacity and clarity, enabling him to combine his wide-ranging knowledge over an impressively broad spectrum of disciplines - engineering, natural sciences, medicine, social sciences and philosophy - into a comprehensible whole... If this book gets the reception that it deserves, it may turn out the most important alarm bell since Rachel Carson's Silent Spring from 1962, or ever." --Olle Haggstrom, Professor of Mathematical Statistics

"Valuable. The implications of introducing a second intelligent species onto Earth are far-reaching enough to deserve hard thinking" --The Economist

"There is no doubting the force of [Bostrom's] arguments...the problem is a research challenge worthy of the next generation's best mathematical talent. Human civilisation is at stake." --Clive Cookson, Financial Times

"Worth reading.... We need to be super careful with AI. Potentially more dangerous than nukes" --Elon Musk, Founder of SpaceX and Tesla

"Every intelligent person should read it." --Nils Nilsson, Artificial Intelligence Pioneer, Stanford University
