The Technological Era

I wonder when "technology" was really invented. Did it start with the primitive invention of the wheel? Or did it start when medieval peoples made their first weapons? Or maybe when the primitive Homo Sapiens began to hunt and gather? Some people call this the technological era because there are so many automated escapes, forms of computerized entertainment. Some people think that we will soon have everything in a form of code, nothing truly natural. Hmm...., that sounds kind of dystopian.
