Brain-net

Google the ultimate search engine, WiFi the ultimate wireless connection, and the bio chip that can be plugged into once brain. These are three technologies that exists in todays world in one of the advanced to moderately evolved stages. Now picture this... We implant a WiFi chip in once brain which can then be used to connect to internet via WiFi thereby accessing the search engines. Now any information a person need can be controlled by the neural connection to activate the chip and query the internet thereby retrieving the results and it could be interpreted by the brain. Now what does that mean.
1) We have unlimited capacity.And unlimited knowledge.
2) No need to learn anything.
3) We could connect to others brain, which acts as a server.
So in short, we have the ultimate super brain.

On the downside
1) One could read others mind... Mind hacking
2) Anyones mind could be controlled... hence a great tool for autocratic governments
