Keep barking about the same for many more years. You proved that we have not invented anything and we just wait for the world to invent something and then just go buy it and use it.
Also why should I be careful on what I am writing? I am not writing any foul language like most of the people in the forum.
If you cannot stand up and take the fact or argue otherwise then you are the one who should get out of this forum and keep thinking about the fact that we invented zero and nothing will work without zero.
