I'd really rather prefer there was some online repository of facts, constantly updated via Machine Learning over publicly available information, which might give up to the second responses of the kind 'Our current understanding is ...'

Is there one already? Wolfram Alpha is close, I guess. Wikipedia is not quite what I'm thinking of. Google is working on something, not sure if it's public though. Their search engine.. also not quite what I'm thinking of.

What/where have I missed?
