Where will it all end finally?

I was watching a show on Discovery in which they were showing the modes of transport of future. The mode of transport was shown primarily to be AIR! Jet packs would be used to move from one place to another. People would be able to evade traffic hassles by easily flying over small distances instead of commuting by roads.
Cool. New innovation, huh? Similar optimism must have been expressed a couple of centuries back when road transport was introduced? It’s in big mess today everywhere. We ate up all lands. On the modern road, where vehicles move today, many years ago, those were the roaming grounds of animals. But we chased them away by killing their habitats and making roads for us. Now we want to chase the birds too away by making more intrusions (apart from Planes) into their roaming air. Does this hunger to save time lead us anywhere? Once it becomes affordable and practical, even jet packs will see Traffic lights hanging in the air. But what after air? I guess we will then spoil other planets from scratch as we did to earth.
