all driven by artificial super intelligence (ASI)
Format: Hardcover
You are peering inside a black hole at a "point" beyond which you cannot see and where no one knows what exists. The point represents a period of time technologically known as Singularity. Even light cannot escape from the point and on the other side it is known only that there is a profound self replicating intelligence greater than our own, all driven by artificial super intelligence (ASI).
Physicist Stephen Hawking writes that "In contrast with our intellect, computers double their performance every eighteen months. So the danger is real that they could develop intelligence and take over the world".
Computer scientist and professor Vernon Vinge writes that "Within 30 years, we will have the technological means to create super human intelligence. Shortly after the human era will be ended".
Our Final Invention is 267 pages of authoritative manuscript that is compelling, fascinating and beyond the fright stage.
The book's author on numerous occasions refers to "we" as if there exists a unified collective engaged in artificial general intelligence(AGI) or artificial super intelligence (ASI). The reality is that some 56 nations are currently in different stages of arcane artificial intelligence designs. They include antagonists such as North Korea, Iran and suicide regimes from the Middle East. Russia, China and the U.S. are the biggest players as is Israel.
The author believes that super computers fueled by nanotechnology will combine to produce ASI trillions of times more powerful than any human academic or intellectual resources. ASI has the potential to eliminate hunger, poverty, disease and even mortality but disruptions of global economies and politics will be in evidence as balance of powers are shifted. Unemployment dynamics will infect bank tellers, retail clerks,
travel agents, loan officers stock brokers....
Computer software designs are so complex, even incomprehensible, that failures are inevitable. The 1986 Chernobyl meltdown, Three Mile Island, and Fukushima were all designed by highly qualified professionals but with complex infrastructures. Under Singularity as computer speeds double with frequency while human intelligence is unchanged, perhaps the musings of Hawking and Vinge will prove to be prescient.
Our Final Invention is 267 pages of a very dark subject which not even a trace of a happy Betty Grable ending is to be found. My time has expired. Perhaps the final words were well expressed by Jaan Tallin, cofounder of Skype: 'A hard-hitting book about the most important topic of this century and possibly beyond---the issue of whether our species can survive. I wish it was science fiction but I know it's not'!

Gripping and Informative, a Must-read
Format: Hardcover
As someone who struggles to finish books in their entirety, I found Our Final Invention by James Barrat highly readable, deeply informative, and utterly gripping. The book contains a powerful message: through competition, distrust, desire and curiosity, humans will inevitably create an artificial intelligence (AI) that rivals or surpasses our own. Thus, it is wise and necessary to invest now in mitigation efforts and potential safeguards -- increased research and advocacy for AI risk and, most importantly, producing friendly AI.
Barrat covers a lot of ground, but his main argument is summarized as follows: Currently, we humans regularly utilize narrow AI technology (technology capable of achieving specific, programmed goals through unassisted human computing -- Siri, Google search, IBM's Watson, etc). We are also experimenting with "black box" tools and techniques (programs where inputs and outputs are understood and measurable, but the processes in between aren't -- genetic algorithms/programming and software that writes better software) and artificial neural networking (ANN), as seen through efforts to reverse engineer the human brain. And, below the surface, there is an ongoing race between world powers (driven mainly by national security, defense, and international business interests) and guided by AI developers to develop and achieve artificial general intelligence (AGI) -- human-level artificial intelligence. The problem is that once AGI is achieved it will be very difficult to manage, and may very well result in the manifestation of artificial super intelligence (ASI) -- greater than human-level intelligence.
ASI could theoretically become thousands of times smarter than the smartest human being alive. It won't think like us, won't want to be ruled by us, and, most crucially, it won't want to be turned off. In fact, ASI would likely regard us as potential fuel for its quest to duplicate and improve itself exponentially in order to achieve its goals.
Throughout the book, Barrat refers to interesting psychological phenomena and concepts (such as the normalcy bias), while drawing on personal experiences, historic events, and interviews with computer programmers, inventors and philosophers, to tactfully illustrate how progress in AI development is dangerously rapid. Adequate checks and balances are not in place to deal with a non-ideal intelligence explosion or hard take-off (AGI quickly leading to ASI).
I highly recommend this book to anyone interested in learning about both human beings and the advancement of machines. I suspect that the prominence of AI, as a research field and topic for discussion, will only increase in time (it already has in recent years -- drones, smart technology, Wall Street high frequency trading (HFT), financial modeling), making Our Final Invention a valuable guide or stepping stone for anyone trying to understand our world and the path of the future.
