How many of the high tech in American blockbusters are real?

So what if it's not real, what about the 1960 sci-fi movie "Star Trek"? Countless young Americans because of the influence of Star Trek, and thus devote themselves to the cause of science and technology, so that today, the smallest to our use of Bluetooth communication technology, to the satellite positioning system, to Motorola's first folding cell phone, to the big automatic door and NASA's hand-held medical equipment, one after another Star Trek in the magic of science and technology, is being realized by the people. One day he will become real!
