You gotta be kidding Ali. You need to read "The Singularity is Near" by Ray Kurzweil.
A computer can now beat the World Chess Champion.
"Dolly" the cloned Sheep.
Genetically Modified crops.
Mapping of the genome.
Full face transplants.
Cell phones are now available to people such as the Masaai, and in Africa there are far more cell phones than land lines.
The Internet.
Online trading for no fees, online gaming, online p**rn, online shopping, online bill paying, online social networking, online second life, online poker, online everything...
v****.
Hybrid Cars.
Ipod.
Wind power now on par with conventional energy in terms of cost per kWh, and solar and fuel cells getting there.
Gastric bypass.
Ability to transplant almost any body organ now, with some form of hair cloning or hair multiplication to come.
Nanotechnology -- with nanonaterials already all around you (and some of these will probably lead to numerous lawsuits in the future a la asbestos).
Child sex selection.
All that and much more in the last 10-15 years (at least in terms of mass consumption, even if the invention occurred a few decades earlier).
Dude, I am an engineer. I know the history of technology to a certain extent.
You say iPod, etc... I was a teenager when the mp3 technology first came out. But Shannon wrote a postgraduate thesis on Informatics back in the 1950s, and the concept of compression was known back then, ie Huffman coding. mp3 is just an extension of the same principles. That's what I mean by "we developed new applications for the known technologies".
Despite your perception of powerful and clever computers, computers are extremely static and dumb. A computer can go through billions of calculation per second, but it's all static and preprogrammed by us. A chess board has finite number (an extremely large number) of moves and the computer can remember certain moves and go through a certain static array to find the next move. It's rather boring and there is no intuition from computer's part. It's a mundane task and it's the brute power of the computer that beats the world champion, not the game play intuition that we humans posses. We don't have clever computers with intuition, and we have dumb boxes that listen to us.
It's the same with mobile phones. Marconi sent the first wireless trans-Atlantic message more than 100 years ago, the first digital data processor was the British code breaking machine in Blechley park and mobile phones are combination of those two, ie, "a new application of known technologies". The spread of the Internet was revolutionary, but not the technology in it.
The IT, as we know it, is an extension to what was known 50 years ago. In the last 50-60 years there is nothing fundamentally new or revolutionary in the IT (apart from shrinking the transistor, as I already said). The same goes for chemistry and physics. I will not dispute that the spread of technology has been revolutionary, which is a different subject.
In the last 20-30 years, there have been developments in pharmaceuticals and medicine in general. Medicine is the only field where there are ground breaking changes with cloning and stuff happening right now. I think the near future will belong to medicine, we might get lucky and gain another 10-20 years of life expectancy.
