Imagine telling a person in the year 1919 what those devices that will exist in 100 years are capable of. >A torch, photo apparatus, soon 8K video camera [***yes, I know,*** they don't understand what *8K* means], portable telephone device in one which can be used to communicate to people from the other side of the world wherever you go and access knowledge in abundance. > It can also play music, record your voice, be used as an alarm clock, a calculator, a note book, and so much more. And it fits into your pocket and in the palm of your hands. > Imagine this device exists in less than a century.
