Amazing Discovery

Hi Steemit Community,
I'm Farhan and I welcome you all to a new series of Amazing Discoveries. Today I have brought you something very special, something the whole world has been waiting for a long time.
I have here a white, square material and a stick. Of course, ask yourself, "what is it again?"
Now, if I move this stick over the white material, then it will discolor in exactly the places where the stick touches the white material. Is not that incredible?
But that is not all. If I use the pencil, which is called the pencil, as you normally see on the computer screen, on the material, you can even read without a screen. is not that about Amazing Discovery ?!
But before you answer, also note that this material, which is called paper by the way, does not need electricity, not even batteries or rechargeable batteries. Of course you can also fold it like your notebook, but not only once, not only twice, but so often, until they can put it into their pocket. Is not that incredible?
And doing so, no power, handy and 100 times lighter than any notebook. You believe you dream? Well then, look at them first:
(Crumpled paper, trample on it) Look, you can still read it. Do this once with a disk or with your monitor!
But even that is not all: you can keep Amazing Discovery much longer than any hard drive that loses its magnetic properties over time, you can take it everywhere and use it both at high and low temperatures, and when you get it No longer needed, it is no special waste, no you can clean your nose with or on the toilet ... You understand what I mean.
Yes, ladies and gentlemen, it is incredible. And I believe it is not too much to say, when I think that our Amazing Discovery one day will make computers, notebooks and playstations completely unnecessary.
Tell me:

1. What do you think is the most important discovery / invention made during your lifetime?
2. What do you think of the way new discoveries are being praised today?
3. To what extent is paper really a revolutionary invention?
4. How will people in the Middle Ages react to the invention of the paper?
   Thank You for your precious time !
