In 50 years many changes can, rather will, take place. Sometimes the changes are drastic, sometimes they are minor, but they happen no matter what.
Many people fear change but it always happens.
Here are some changes that I believe will have taken place by the year 2050. In 50 years transportation will be very different. Cars with detachable wings will be the hottest new thing. By the year 2050 technology will have started to overflow. Computers will be very advanced and robots will serve as servants and helpers to humans.
