Wolfram|Alpha is pretty darn cool, but what scares me is reading about what's under the hood, so to speak:
Today, Wolfram|Alpha uses existing models from science and other areas, then does computations based on these models.
But what if it could find new models? What if it could invent on the fly? Do science on the fly?
That is precisely what NKS suggests should be possible. Exploring the computational universe on request, and finding things out there that are useful for some particular specified purpose.
Great. Skynet, here we come. And we all thought Google was the evil empire in our midst.
I do dig the Schott's Original Miscellany site design, though.
