Scientists predict that “within a few years, we [will] have an artificial intelligence that is much, much more intelligent than a human brain is physically capable of being.” Some people fear that sentient machines will rise up and destroy us, but other, more optimistic scientists like Stuart Russell believe that “very smart computers could solve all our problems, including climate change.”
Reminiscent of Ripley’s heavy-lifting-turned-alien-killer robot suit, scientists predict that humans will be able to use (much smaller and more compact) exoskeletons to significantly increase their strength. It will not only make a mover’s job much easier but will also help those suffering from muscle and/or back injuries.
Some scientists, like Shimon Whiteson, even predict that humans and computers will become one. They will be so closely intertwined through the process of constantly augmenting our brains and bodies, that they will one day be indistinguishable from one another.
Others predict that we will have machines able to tap into our subconscious, record our dreams and then replay them. They have been working on such a machine in Japan, but its accuracy rate is only 60% at the moment.
With droughts plaguing various areas on Earth, scientists are thinking of ways to get more water. NASA scientists have proposed "sending a rocket ship to an icy comet and bagging the comet (in a really big bag)” in order to harvest it for water.
Speaking of space, NASA plans to send a crew of up to four astronauts into space by 2021, possibly even as far as Mars. Even the private sector is looking to get in on the action by developing space tourism opportunities for the common man.
Scientists have already managed to produce a burger in a petri dish (yum?) and “print” candy out of sugar (yum!). Some say that in 10 to 20 years, this form of food production will be the norm and we will not need to kill animals anymore. (Cows and vegans rejoice!)
In the future, we will develop new building materials that will transform our cities into places that respond and harmonize with the environment. Buildings will “breathe in pollutants, clean wastewater, and use sunlight to make useful chemicals, energy, heat and vibrant vertical gardens.”
