I don't see Wolfram Alpha and Google and competing at all, but rather as complimentary services. Wolfram Alpha looks excellent for research and specific maths/science related queries, whereas google excels in general search. If they can get their content to a respectable level for any given subject area, eg physics, I can see Wolfram Alpha becoming a valuable tool, worth paying a reasonable subscription to use.
