text: In my opinion parents and students should get the idea of using techonology its way easier to detect peoples emotions instead of just guessing or thinking you know how they feel. They shouldn't have a problem trying to make the place better.Would you ever dream of a taxi cab that has no driver and can drive you around? Google is making cars that require no drivers. Although this is a very neat idea, it is extremely expensive. This idea would work if all of America was urban land and not so many non urban areas. I think driverless cars are one of the biggest wastes of money we have came up with so far.
