We could have had flying cars

Long long time ago one loser of the pack dude was still banging on his rock trying to break a piece that would be sharp enough to get him into hunting team but he picked a wrong type of rock and didn't know about it..
but he also didn't know that his wrong type rock not only it will not let him in the hunting team but also it will delay humans from having flying cars for about a thousand years or even more! That dude was the dude that became famous (in his own time period) because he invented the most useful thing called wheel.. damn you! why didn't you go and explore electricity? huh? see, if you did invent the way to store and use the electricity we'd be flying by now! we would live the Jetson's life! like fly around, have a robot cleaner and a dog with an antenna! Everybody would have antenna! We could have computers plugged/installed in our brains so we could play video games, blog and socialize while we sleep (it's 8 hours!) And be awesome! nothing circular in our electricawesomelife! Skip all the roundabouts, DVDs and other wheel-idea-using things! really, why the hell did you not think of the origins of fire when looking at it? Yes, fire is awesome but did you not think of how awesome it would be to have the lightening in your pocket? The Lightening that made that awesome fire? Really? And we still think we're the smartest beings...

We could have had flying cars and a summer house on the moon or.. or..
