Wolfram's long-term goal is to make all systematic knowledge immediately computable and accessible to everyone . They aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything.
Wolfram|Alpha is not a search engine. It's a computational knowledge engine: it generates output by doing computations from its own internal knowledge base, instead of searching the web and returning links.
