Just Google it - typical response when you don't know something.
Now what would happen if you could have a direct link to the net via a brain implant? Instant access to the world's information, just by thinking about it.
Obviously Matrix style 'downloading' of skills would be cool too, but just the ability to access random stuff on the net just by thinking about it would be huge step forward. No more 'learning', because it's instantly accessible.
I don't think it's that far off either.
Slooooow day at work today...
