Some random evil thoughts

Assuming that the artificial intelligence like Wolfram Alpha continues to evolve, and that the goal of Google is to provide information for the people around the world, there should be one day that arbitrary question can get answered by search query from Google. Then this will signify the extinction of consulting firms like BCG or McKinsey.

However, the consulting firms are providing information for money, big big big money. So should Google provide all kinds of information for free? And is charging money for information evil? Or is giving part of information for free and charging money for some higher-level information evil? Hmmmm
