"sponsored suggestion to “Buy a restaurants are nearby at Wal-Mart.”"
EDIT: I guess it's worth pointing out, however, that Google Now doesn't show ads.
Not yet.
Word of mouth is considered the best form of advertising you can get. Almost 100% of the time it's not even paid for.
With iPad, for example, it was very clearly positioned as a media consumption device from the very beginning.
With Google Glass, potential customers are being asked to brainstorm what they would do if they had Glass.
Does not seem particularly innovative to me.

To continue indexing and searching Google has to make money. The most obvious path to billions is leveraging the indexing and searching into ad revenue.
What makes me more nervous than Google being capitalistic is Google not having boundaries about who/what/when/where/how they will index the whole world's data.
