Why don't you read an article or two. It'll help keep you from making a fool of yourself.
- darawk 8y agoMaybe you should read them. Neither remotely supports the point you're trying to make. Unless all you're trying to say is "people have been digging tunnels for a while". Which is about as useful as pointing out that people had been riding horses for a while so transportation was probably as efficient as it was going to get.
- wcarron 8y agolol ok buddy. Have a good christmas. Maybe someone'll buy you a coursera on reading comprehension!
- darawk 8y agoYou have a good way to signal that i'm wrong, and a bad way. The good way is to quote the paragraph you think supports your point. You're choosing the bad way, which is pretty solid evidence that you're the fool pretending to knowledge, and you know it.
