That is why we need to experiment with better tools for information manipulation and discovery (I did not say tool for thought).
I'm, like you, quite familiar with the explosion in digital music. Don't you think we need better designed "tools for music creation" to explore this infinite ocean of sound possibilities that has opened before us? I believe we do.
It is very similar for Knowledge. But given the more fundamental, "personal" and malleable nature of "thought", this will take a lot of guess work (and stupid ideas). In the long term though, I believe we need these better tools to adapt ourselves to this almost unhuman ocean of (mostly outer) information.
