End-of-mankind predictions about artificial intelligence, which have issued from some of today's most impressive human intellects, including <a href="http://www.bbc.com/news/technology-30290540">Stephen Hawking</a>, <a href="http://www.theregister.co.uk/2015/05/03/ai_expert_nick_bostrom_talks_to_el_reg/">Elon Musk,</a> <a href="https://www.washingtonpost.com/news/the-switch/wp/2015/01/28/bill-gates-on-dangers-of-artificial-intelligence-dont-understand-why-some-people-are-not-concerned/">Bill Gates</a>, <a href="http://betanews.com/2015/03/26/apple-co-founder-steve-wozniak-warns-of-the-dangers-of-artificial-intelligence/">Steve Wozniak</a> and <a href="http://www.dailymail.co.uk/sciencetech/article-3165356/Artificial-Intelligence-dangerous-NUCLEAR-WEAPONS-AI-pioneer-warns-smart-computers-doom-mankind.html">other notables,</a> have generally sounded overly alarmist to me, exhibiting a bit more fear-of-the-unknown than I would have expected from such eminences, especially the scientists. But that was before I saw reports on the self-aware robot.
