text: In Conclusion, technology that reads emotions can be very useful. First, how it's uesd. second, the value it has in schools. Third,it can make it easier to detect someones emotion.Having a car that will drive on its own is cool and all, but when you think about it it could be very dangerous. People in todays society are very lazy. All most people do now in days is sit at home, sleep, eat, or watch televison. So I dont think having a driverless car is such a good idea.
