You seem to be conflating a few things here. The "expectation of privacy" is what really matters. The technological advances are a means to an end. If you expect privacy in filming your family gathering in your private residence, then Google Glass or no Google Glass, you would not expect the world to see. In fact, one could argue that the idea of "circles" in G+ creates the expectation of privacy by giving you a (false) sense of control over who has access to it.
The 4th amendment language is really quite amazing: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
When I think "papers, and effects" in today's world, that includes my smartphone, computer and all "papers" that are handled by Google and any other provider or stored on any medium I can possess. Just like people of 200 years ago did not expect others to read their mail, I don't expect it now. (Though I understand that it is now common practice.) Unfortunately, because such concepts have been abused and twisted in the court of law, Google now finds itself compelled to argue that there is no reasonable expectation of privacy when using email[1]. Do you expect your postman to read your letters too? Are these that different from an email?
If we, as the society (or the people), establish clear boundaries on what we expect and demand it, all will be fine with the world. A "shadow" profile on Facebook aimed at selling ads is a far cry from contents of my private correspondence. In fact, I welcome more relevant ads - they are less annoying. But that does not mean I will expect that there is no boundary between my private and public persona.
