It isn't. The government is one actor, and certainly has many contributions - the Internet is a big, obvious one - but there are certainly a lot of private actors that count for something too. Apple, IBM, and Microsoft come to mind. So "product of a planned state-controlled economy" is what I would call either "science fiction" or "wildly inaccurate", just as I would say that "high-tech is entirely the result of the free market" lunacy as well.

Actually, my wife does research at a university, and I very much do think there is a lot of messiness in science, and think it likely that it's vastly underfunded - in part due to the fact that it's difficult to bring market mechanisms into play for things like basic research.
Or for that matter, high tech. Oh, you thought high tech isn't a product of a planned state-controlled economy?
