I don't understand why computers need to figure out laws of the universe. There are so many dying concerns already on this planet - which can be solved by a man machine symbiosis. Personally I think such ideas are cool, but are not of great/immediate use. It reminds me of the machine built to find the answer to the question "What is this life about?" in "hitchhiker's guide to the galaxy". 42!
