Technologies and who did the best job

I think Charlie did the best job simply because he built a computer for his grandma and satisfied every need that he thought would be best for her.

These new technologies relate to computers in a few different ways.
1) All those implants of artificial body parts are managed by computers. Computers help calculate exactly how to implant a certain part. Some of these artificial parts are computers. For example the eatable chip or pacemaker.
2) These parts relate to computers by raising the question of when do we have to draw the line between human and inhuman. It's very cool to keep a person alive through a pace maker and that a computer can give me access to infinite knowledge with the click of a button. But when does it become unethical, to keep advancing into making life "easier." Or can we keep going until we find a a way to live forever?

The most amazing invention to me is the retina implant. Our eyes are the biggest contributors to our perception of the world. and to be able to give this gift to a person who has lost all sense of up down, color, and depth, I think is truly incredible.
