Technology is great when we all can benefit from it, not just the few!I'm thrilled to see some amazing inventions that will shape our future!This should be retitled "inventions that will never be available to anyone because of their impracticality".These things might be available, but most can't even afford rent or food. SO......WHO CARES!!!The music is so repetitive that it almost made me watch something else. But I just hit mute for a few seconds between the mostly impractical inventions.
