For example, what if back during the 1800's, there were already smartphones. I mean, the materials that we use to make these advanced machinery, (I'm talking about the elements), have always been there. Carbon, Tin, Iron, etc. These things have always been there. And also, atoms, which are involved in electricity. Humans are made of atoms. These things have always been there; they were just waiting for somebody to discover them. What if that was speed up?
