I can see Google responding with a similar offering, especially with their impending Squares release. It'll be interesting competition flaring up in this space.
I don't think Wolfram Alpha is that. I think its goal is honestly too ... computational, logical, factual ... to have the broad appeal of Google. But I don't think that because something is fundamentally different than Google means that it's not the fabled Google killer.
Take a DVD player as an example, if he was inclined to load the data I could put in a model number and it could show me the technical specification, picture, manufacturer etc.
If I put in two model numbers he could compare them. Could he include in the contents things like product reviews? (is the only problem a trusted source for the data?)
Or, he seemed to have a link for movies - presumably if I type the name of a movie he can list actors, year of release, sales gross etc. If I put in a band can he tell me whether they're touring, back catalogue?
Its obvious from the demo he hasn't been building something to help me pick a DVD player to buy, but does anyone know if this system is likely in the future to support this kind of thing that would be useful to the layman? because that's what might scare Google (or not if I'm barking up the wrong tree here).
