Summary

The Future of Humanity focuses on human space travel and colonization of other planets.  Futurist Michio Kaku explores how developments in robotics, nanotechnology, and biotechnology could enable us to build habitable cities on Mars, nearby stars might be reached by microscopic spaceships sailing through space on laser beams, and technology might one day allow us to transcend our physical bodies entirely and achieve immortality.

Quotes 

“I sometimes think about how easy it is for a nation to slip into complacency and ruin after decades of basking in the sun. Since science is the engine of prosperity, nations that turn their backs on science and technology eventually enter a downward spiral.”

 

“Do we have enough food to feed the people of the world as they become middle class consumers? The hundreds of millions of people in China and India who are now entering the middle class watch Western movies and want to emulate that lifestyle, with its wasteful use of resources, large consumption of meat, big houses, fixation on luxury goods, et cetera. He is concerned we may not have enough resources to feed the population as a whole, and certainly would have difficulty feeding those who want to consume a Western diet.”

 

“Claude Shannon, the father of information theory, once declared, “I visualize a time when we will be to robots what dogs are to humans, and I’m rooting for the machines.”

 

“It’s easy to imagine that, in the future, telepathy and telekinesis will be the norm; we will interact with machines by sheer thought. Our mind will be able to turn on the lights, activate the internet, dictate letters, play video games, communicate with friends, call for a car, purchase merchandise, conjure any movie-all just by thinking. Astronauts of the future may use the power of their minds to pilot their spaceships or explore distant planets. Cities may rise from the desert of Mars, all due to master builders who mentally control the work of robots.”

 

“One reason why childhood lasts so long is because there is so much subtle information to absorb about human society and the natural world.”

 

“An even more advanced form of uploading your mind into a computer was envisioned by computer scientist Hans Moravec. When I interviewed him, he claimed that his method of uploading the human mind could even be done without losing consciousness. First you would be placed on a hospital gurney, next to a robot. Then a surgeon would take individual neurons from your brain and create a duplicate of these neurons (made of transistors) inside the robot. A cable would connect these transistorized neurons to your brain. As time goes by, more and more neurons are removed from your brain and duplicated in the robot. Because your brain is connected to the robot brain, you are fully conscious even as more and more neurons are replaced by transistors. Eventually, without losing consciousness, your entire brain and all its neurons are replaced by transistors. Once all one hundred billion neurons have been duplicated, the connection between you abd the artificial brain is finally cut. When you gaze back at the stretcher, you see your body, lacking its brain, while your consciousness now exists inside a robot.”

 

“If we scan all the life-forms that have ever existed on the Earth, from microscopic bacteria to towering forests, lumbering dinosaurs, and enterprising humans, we find that more than 99.9 percent of them eventually became extinct. This means that extinction is the norm, that the odds are already stacked heavily against us. When we dig beneath our feet into the soil to unearth the fossil record, we see evidence of many ancient life-forms. Yet only the smallest handful survive today. Millions of species have appeared before us; they had their day in the sun, and then they withered and died. That is the story of life.”

 

My Take

As a lifelong lover of science fiction and futurism, The Future of Humanity was an fascinating read for me.  Kaku writes about lots of interesting ideas in a manner that is accessible to the lay reader.  I also learned a lot.
