What innovation can't you live without?
I'm working on a project and am in search of what you consider to be the top technological innovation in history.
Something that makes or would make your life easier or more enjoyable. It can be historical like fire, or the light bulb, or a present day gadget/software/toy, or even something completely made up that you'd like to see in the future.
One answer would be great - but if you feel inspired, submit more or expand on why it's important. Thanks!
