What will a PC look like in 20 years?

Answer 1

It is an exercise in Science Fiction to try to state what a PC will look like in 20 years. In the direction of technological optimism, I could speculate that in 20 years, your PC will be a tiny device the size of a quarter, which will be surgically implanted in your head to create a direct neural interface of magnificent efficiency. It is also possible that the PC has already reached its mature form, and it will change very little over the next 20 years. It is even possible that people will no longer be using PCs in 20 years. Many things are possible.
