It happened a lot in last 20 years. Like downloading videos or mp3s on a tiny piece of plastic from your car on the road while you get told the way from it.
Or actual devices which are able to connect with your brain so that blind people can recognize something or if you lost a Hand and you get a robot hand which is able to move through your mind.
hybrids nightvision in cars the possibility to fly in the space if you have 100000 Dollar. Or a Rover on mars which drives around the mars for two years.
The possibility to breed human ears on a mouse. Or make the mouse shine like a deep sea fish. Or to clone. Or the possibilty to implant eggs and semen in a third person so people dont have to stop work during pregnancy. Medicaments which allows people with Aids to live 30 years or longer. Or a vaccination against cervical cancer.
Graphics which evolved from dots to almost life like. The possibility to have a remote control for animals like mice. Robots which are able to walk stairs without taking hours to do it.
Internet for everyone with 10-100-1000 times the speed.
Plans for a moonbase india and china actually are able to send things in to cosmos china even humans. A 818 meter skyscraper more then 2 times higher then Empire state building and artifical islands gaint networks of computers/consoles which solve elemental problems for science.
Humankind discovered 400 extra solar planets and we are actually looking for a second earth in space and maybe we will find it with Kepler. in the next 2-3 years.
It happend a lot. Things like beaming and spacetravel for everyone to distant planets suns are completly out of reach and always been out of reach for next centurys (beaming for next 100000 years atleast) A matrix is more realistic then doing interstellar space flights.
The humankind achieved more then ever before in history like the decoding of the human genome 20 years ago people thought it would take 100 years but no we did it pretty fast and it can be used against crime.
It happened even more than we thought. Flying cars wont be here anytime soon our technology is too inefficent for that now. But I can imagine in 50 years there will be a hotel in orbit of earth and probably one on the moon. The whole life will change even more due to internet. Everything will change. There is one major thing which if possible would change the whole humankind for ever.
The future is already here but most of the things which were futuristic 20 years ago were physically so hard to achieve that it was clear from the beginnig it wouldnt happen. But most things which actually happened are pretty futuristic and the people from 1990 would hardly believe what happened actually. What we see now is just the first step everything will be improved the technology in 50 years will be so advanced we probably would have difficulties to believe it. The development is faster then ever and the difference in 50 years will be bigger then the difference in the last 50 years. And 1960 our technology of today was completly unthinkable. We will live atleast 90 years because if average life expectation is increasing like the past 50 years then 90 years will be the average life expectation and new medicine will allow us to live those ninty years in a good condition.
If nothing happens like a giant war we will have a bright future.
