And to be fair with Asimov, he saw some of that for example with "U.S.Robotics", a fictitious private company that invented the positronic brain and had a monopoly on that business. Also, his Encyclopedia Galactica is the creation of a large group of "encyclopedists" who are basically academic elites, something we could see as a Wikipedia-like except that it wasn't produced by millions of joe schmoes but rather by a kind of priesthood of professional intellectuals. (Foundation makes these people work in a centralized organization, but that happens in a late period of the galactic empire, it's my impression that the origins of the Encyclopedia are way more descentralized.)
Absent any existing examples, the effects brought about by the modern Internet, smartphones, collaborative open source software development, generally less rigid organizational hierarchies, etc. would have been very difficult to visualize. Indeed it would have seemed almost alien.
