In 100 years we won't be much farther along than we are now. We may have flying cars or jet packs but in all reality we will just be humans. Back in Edisons day steel was a key furnishing for a rich person but what he didn't realize is the price of things would just increase. So we have been reduced to laminated partical board. Some future this is. We are polluting our air more now than we were then. We may live longer but almost half of Americans spend their life in jail or prison. Most cannot make their way to the next week with out a welfare check or some support from the tax payers.
