whats the next big thing?

If we look back at the evolution of humane beings I believe that the last 100 odd years were the best of our evolution, in the last 100 yrs we have learnt to fly, to use energy out of fossil flues, and other alternative flues. Then came in the atom and the nuclear energy.. Yes the good and ugly part of it, then we have invented and equipped our self with the computers, more importantly discovered and learnt the art of using computing in our daily chores of life, internet was the next big thing to happen, which has actually shrunk the world. Biotechnology has shows us what promising future can be by answering the problems of reducing food production. The mobile phone, which has made humans more humans by easing the means of communication.

May be I have not listed all the important events and discovery, yet I believe that it was electricity, which has been the common thread that has woven all the industries, its been the OS of all the industries. Electricity has propelled the entire revolution, and has changed the life that we live today. Come to think of it we would not have been this smart a species if electricity was unknown to us. Without electricity how would have used computers and internet, which today is a huge source of learning, with out the Television the would have been mere geographical divide, and the knowledge of one society or a country would remain only with it.
It’s been a combine drive of electricity and petrol / diesel which has given the world the concept of transportation.

I wonder what would be next big thing that we would reinvent the human species, the next big thing which will be as potent as electricity and fuel, the next big thing that will be omnipresent, and drive the future economies.
