As we all know, the rate at which technology is advancing could be compared to the speed of light so to say. If all this could happen in 28 years then i can say in the next 28 years to come, wed look back at the present smart phone and marvel at the evolution which would have taken place. Probably smart phones would have their own brains and knows what to do without being told, just exaggerating but the next 30 years holds promises of the new world technology.
