Ray Kurzweil, in his book The Age of Spiritual Machines published in the year 2000, made the astonishing prediction that by approximately the year 2020, computers would exceed human intelligence. Fast forward to 2025, and we have ChatGPT 5. While OpenAI does not call it Artificial General Intelligence, I find it close. It gives plausible answers to any question you ask it, on any subject under the Sun, and a large majority of its answers are quite, or completely, accurate. Kurzweil is a technologist and futurist, and what is more interesting about his book is the other predictions he makes. He talks about the possible properties of aliens from another planet visiting our Earth, nanobots, which are self replicating tiny nanotechnology based robots, human machine integration, the end of mortality, and so on. All this before the end of the 21st century. I haven’t yet gotten around to reading his 2006 book, The Singularity is Near: When Humans Transcend Biology, but I’m looking forward to it.
