Pluggable knowledge base for human brain

I bought my first 1GB USB flash drive in 3300 Indian Rupees ($80 approx.) in 2004. Nowadays I see 4GB flash drives are available in $14.99. It's so cheap these days and I hope someday we are going to have 1TB USB drive in $50 or less. USB has become universal and you can find it in computers, cameras, media players bluetooth devices, external drives; all most any device that's pluggable with a computer.
I remember the movie Terminator to be good instance of man-machine fusion. Imagine someday we all will have an USB port attached to our heads. All our knowledge base will be made available in market in USB drives so that we can plug that into our brain and use them. An idea called Brain-Computer Interface close to this is already out in the market (http://en.wikipedia.org/wiki/Brain-computer_interface).


The OS vendors can see a nice business case in developing a firmware to install in the brain so that it understand and interact with the USB port.
An interpretation layer to translate the data from the external media in a format that the brain can understand (may be an electric pulse language :))
A lucrative business opportunity for Google to come up with a search utility to look up the knowledge base and find out the required material and supply it to the brain :)
We will have knowledge bases available for a doctor, an engineer, a lawyer, software engineer and whatever else you can think of under this sky.
If I need to be a doctor in the morning a pilot in the evening and a cook in the night, I can do every thing very skillfully with all these equipments :)
Well you will still need to practice if you are going for a swimming competition.

Yes you are correct I have some free time to relax my brain and talk rubbish :)
