We talk about invention and innovation.

We talk about inventions and innovation as though the best things out there are the Internet, iPads, or smart phones. Or perhaps more simply, trains, planes, and automobiles. Which one is most important, the best, or the greatest? Which one has had the most impact on society? Today the debate would probably be in favor of computer technology, but is it? Well, some would say, "Nope, not really, it's farming." Where would we be if we didn't have it? Give up?
