There were a lot of important things invented before cell phones and operating systems, like starting from the wheel and the fire, you know? What we call USA today grew on immigration, isn't this speak for itself? But why am I talking generics when some of my engineering teachers (the young ones) left for USA even in my university study years! The qualified people, the ones that takes a lot of time and resource to train - taken! Could be here all night? Really? P.S.: BTW, the knowledge on which transistor relies did NOT occurred in USA, and networks similar to USA's ARPANET were developed in other countries in the same period, so the fact that Internet has an USA origin is purely incidental ...something that may be true for a lot of other things.
