According to the article (and doing a little math) a 10 cubic millimeter data chip would store 100 years worth of video. One could document one's entire life, assuming the data input device existed to compliment the memory chip. Robert Sawyer wrote about this possibility in his Neanderthal Parallax novels, and Greg Bear also wrote about it in his novel Eon. Potential uses:

1. Self-defense: No more my-word-against-his bullshit. I've got video evidence now!

2. Photographic memory: Never forget what you saw, or was supposed to see, on such-and-such a day.

3. Share memories with others: Possess the memories of others! If our memories make us who we are, then be someone else. Identity could become incorporial, except for that sticky point of biological memory (the brain) which would still be the real person.

4. Human encyclopedia: have the entire library of knowledge downloaded into your head. Would we still need to learn? Probably. The brain doesn't absorb information that fast.

5. Propaganda: People are encouraged to think certain things by censoring the information on their chips.

6. Statistics: Enormous amount of information could be collected about people's behaviour.
