What would you consider to be the single greatest invention in the history of the world? Why?
My first response to this is, well, the toliet! I mean could you imagine doing your business in a shack in a hole in the ground?? Then I thought maybe I could do that if it's absence meant I could travel long distances in a short amount of time. Right, the airplane is a significant invention. Then that train of thought led to, well how would I get the airport? The car. The car changed life as our ancestors (grandparents for most of us I guess) knew it.
And what about the internet? Definitely the biggest invention of our lifetime? y/n?
The bottom line here is that I can not decide.
