- Eventually computer chips, theoretical physicist Michio Kaku avers, will cost a penny, which is the cost of scrap paper. They'll be so pervasive, they'll even be attached to your eyeball.
- They'll be in your contact lens, allowing you to blink and go online — you'll have access to the internet and will be able to access the knowledge stored on the internet.

- Many mysteries remain such as where consciousness originates and how we evolved such a multipurpose mind.
