I think you misunderstood the point of the post, it's not that G+ will change everything today. It won't. It can't. It just started and most of my friends aren't on it either, but the technology and the UI they have come up with is quite enviable and we may be seeing the future of electronic communication. G+ is very well positioned to change email given the popularity of Gmail. Forgive my seemingly impetuous post, but I think we may be seeing the future.
