ICT is overwhelming and it is evolving so fast. New stuffs just pop up every minute of everyday. You just find yourself surprise one day you wake up your thing is already obsolete -that's what happens if you can't cope up with the evolution of ICT. Right now I am sharing this thoughts with you- what happens after 30 years? How would it be like in the digital world? I am even thinking that "digital" would be a thing in the past just like analog. How about the villains like viruses, spywares, and the like? How about new software and hardware?
