What would the world be like in the mid 21th Century?
In my imagination, people in the mid-21th century will no longer have to drive the car by themselves, as the car can be driven automatically using computer programmes inside the car. In addition, these cars will not run on petros anymore, instead, they will be using solar power or simply electricity from home.
Other than the cars, people in the mid-21th century will not use normal desktop computer anymore, but people will computer-in-hand, which is a small computer that has the size similiar to a cellphone, and these mini-computers run on solar power too so people will not worry about running out on the battery anymore.
