I would invent something called: The Hard Drive.
It's a program as well as a small internal tool implanted in a child before birth. After he/she is born and at about 6 years of age. A cavity in the child's mouth appears. It has a receptor for a hard drive. Hence the name. Anything downloaded on the hard drive can be downloaded into the child's mind. Not only can it give data, but it can also remove it. There is a single password that deactivates a Firewall in case the hard drive is stolen or lost. This invention can aid in spying intelligence, hard-to-understand concepts, almost completely eliminate schooling and educational learning, but still can pose a danger. Needing trustworthy users and subjects. Though, if used wisely, it can be a tool with infinite possibilities to make the world a better place.
