Peter Norvig put it best, when he said: "The semantic web is the future of the web and always will be."
Norvig is a smart guy, and maybe he meant something different by that quote than the obvious reading, but at first blush that sounds silly. If he's saying "The semantic web "always will be" the future because it will never happen, then he's objectively wrong. The semantic web is here and has been for a long time.
The key thing to remember though, is that the semantic web is about machine readable data... semantic web technologies are not, by and large, something end users interact with, or even need to know about, themselves. They empower things for developers, but are mostly invisible to the average user.
Google, Yahoo and other major search engines have been extracting semantic data - in the form of RDFa, Microformats, etc., - and using that data for at least 10 years now.
OTOH, if Norvig mean that it will always be the future because it's always evolving, adapting, and growing, then, well, yeah... of course. And that's exactly where we are. Semantic Web tech just keeps getting better and more useful.
