Oh my oh my oh my. The human imagination is one of the most powerful things that we have discovered so far in our simply existence of 50,000 years being sentient (Self Aware) we have a long way to go, maybe we never will, in the line of inventing newer devices.
At CERN (Scientific Community based in Switzerland) a village full of the world's brightest are attempting to understanding the fundamental conditions surrounding how the universe was created, it's leading into fields such as trying to synthesize Anti-Matter, an infinite amount of energy that if tapped could power a continent's worth of electricity from a single gram of it (Though it's suggest it would take 14 Universe's lifetimes to synthesize just one gram of the substance)
We have yet to discover a fundamental formula to discover the Graviton, the particle that thus maintains gravity everywhere in the universe, and if it could be manipulated, send anything ANYWHERE in the universe. This of course would be a giant leap into space travel and one day, colonization of another planet.
Artificial Intelligence, now many a movie has been made on the subject and whether the realization it could or could not happen is up to debate, but there have been robotic models of brains created and stored in little cube shaped robots that when given a task, one took over the entire groups thought processes and together worked to complete whatever mundane task put in place by them. Do note we got a long way to go.
Holographic computers and phones are just now about to come to the cusps of reality, if you haven't checked out Summer of 2012's upcoming iPhone 5 then I suggest you do, they will be incorporating a holographic keyboard and screen that will allow you to type on a plain surface of wood or watch video suspended in air with no backdrop. Futuristic...yes lol :D
And finally medical science is attempting to clone a living person's stem cells, if it could be created in large enough bulk then accidents that would otherwise be life threatening could easily be repaired with organs grown in an incubator within a manner of hours to help sustain the life of a dying person. Medical Scientist predict that the present generation of youths (ranging from 20 to 30) could possibly see an average life expectancy of 125, though it could be longer since it's predicted in the next 25 years people could go into a doctor's office and get routine maintenance on their aging body. I'm not talking about plastic surgery to look younger or botox, but literally taking years off your aging and giving you a healthy body of 25 or 30 while your real age is 77. Wouldn't that be a trip?
Advancement in technology is ongoing and these are just a few that I can give off the top of my head aside from Silicon Valley's upcoming video film, it's not the proper word for it, but it's a laptop that unrolls like you would a paper or parchment and stored in a cylindrical case. Once unrolled you can turn it one like any type of computer and use it for whatever they decide to program it for. The applications of such a product is many
