Brain-computer interfaces (BCI) are any manner of technology that might link the human brain to communications networks such as the Internet.
BCI is typically a computational system implanted in the brain that allows a person to control a computer or other electronic device using electrical signals from the brain.
It is possible to see BCI more expansively as a platform for cognitive enhancement and human-machine collaboration.
The BCI functionality of typing on a keyboard with your mind suggests the possibility of having an always-on brain-Internet connection.
Consider what the world might be like if each individual had a live 24/7 brain connection to the Internet.
Just as cell phones connected individual people to communications networks, BCI might similarly connect individual brains to communications networks.
