I know that is sounds funny but the teleportation device, if it ever becomes real, will be the biggest boon to mankind ever. Think of the possibilities. You won't need oil for your car cause you won't need a car. About 50-75% of the cost of the stuff you buy is transportation cost. Digging minerals, shipping ore, shipping smelted bars, shipping finished steel coils, shipping stamped panels to another plant and shipping the finished car to your dealer. No need for grocery stores - just order what you want online and they teleport it to you. Who needs an airline - just teleport youself to Vegas.
