This problem will become more acute as all-day wearable AR devices become mainstream and the state of the world is recorded and parsed by a distributed network of them. You’ll be able to check the quasi-real-time and historical states of a particular restaurant, pull up the exact menu that was being served yesterday, as well as reviews. None of this will be indexable by Google. However, Google is particularly well positioned to leverage their technology and resources to be a leading player in the market for such devices.
