Anyone who said the wheel has to be right. Think about the wheel and the wheel shape and what they are used in. No wheel no cars, no wheel shape no gears, no watches, no conveyors, no motors, no electricity, no running indoor water or plumbing of any kind. no WHEEL= We are still running around in animal skins dragging our women around by the hair. Not so bad if you think about it right?
Without internet porn you wouldn't have streaming video. No youtube. Also image galleries, live chat...hmm...webcams. The internet porn industry helped greatly in developing those.
