Knapping is the use of stone tools. These stone tools were used to help get the meat off of the bones of animals as well as for other jobs. These were used by what we would now refer to as "cavemen". One really interesting thing is that they would pass the skill of making these tools down from generation to generation without a language. Video

The lie detector was first created by a Berkley police officer. He thought that spikes in blood pressure would show guilt. People would sometimes just admit their guilt from the threat of the polygraph. That being said polygraphs are not considered credible because it has given false results.

Clippy was one of the first pieces of artificial intelligence. Introduced by Microsoft this little guy would pop up and try to help you write your paper.

The idea of Neural Prosthesis has been around since the 1950s with things such as cochlear implants and visual prosthetics. This area of medical technology is still improving. In the book "The Heart of the Machine" there is a story set in the future about a boy who gets a neural prosthetic to help with his autism so that he could understand others' emotions as well as social situations. This is something that could very well happen in the future as this technology evolves.

I think that by 2100 it is possible that we could have holograms. We will be able to project things from our phones. This would be really cool when it comes to facetiming people. We will be able to see their full body. In addition, it would be fun when watching movies as it would make it more immersive.
