1. I imagine in the future there could be cars that drive, stop, and park themselves. The car will be so independent that there will a HD movie screen on the windshield.
2.People will communicate through using microchips implanted in their wrists that will send and recieve calls to any phone number
3. There could be robot teachers (programmed by bing and google) to instruct students online from the comfort of their homes. There will be educational commercials on every station.
4. I doubt will be world peace or equality any time soon unless everyone learns to listen and accept one another and respect and understand people who are different from us
