The Five Forces reveals how technology is unleashing forces that will forever alter our lives, politics, and society. Learn more about nanotechnology, transhumanism, the future of space exploration and colonization, super human computers, and so much more! Discover what lies in our future: How will humans change as we merge with our machines, embracing transhumanism?What happens when intelligent algorithms make all the decisions?Should we connect our brains directly to the Internet?And are we entering an age of simulated realities? The Five Forces takes you on a journey to see what the most brilliant minds of our age are dreaming up. Hoffman reveals how new scientific breakthroughs and business ventures are poised to reshape our lives and turn science fiction into fact. With scientists in Japan creating humanoid robots, Silicon Valley biohackers boosting their IQs, and Chinese labs developing human-monkey chimeras, Hoffman gives an inside look at the limits of what’s possible today and the impact these developments will have. Mass Connectivity What happens when brain chips connect our minds directly to the internet? Will we be able to boost our IQs, exchange memories, and communicate with our thoughts? Or will this turn into a nightmare, with corporations reading our minds, hackers overwriting our identities, and governments controlling our actions? Bio Convergence Now that we can decode the building blocks of life and create new lifeforms that never existed before, what comes next? Will we conquer disease, resurrect extinct species, develop superior plants and animals, create DNA-edited babies, and even spawn other intelligent beings? Human Expansionism Is it our manifest destiny to colonize Mars and extend the human race beyond the limits of our solar system? How will technologies like space travel, new materials, and nanotech transform our civilization and open up new horizons we never imagined possible? Deep Automation As our machines become capable enough to do every job better, faster, and cheaper, how will this affect society? Will we wind up delegating our most important decisions to data crunching algorithms? And does this mean our machines will end up running our economies, our corporations, and even our lives? Intelligence Explosion As soon as we create a superintelligence that far surpasses human capabilities, what will happen to us? Will we be able to control our machines, or will they eventually control us? Are we headed for a paradise of plenty, where our technology eliminates hunger, disease, poverty, and war? Or will this be the end of our reign as the rulers of the planet?
