It would be interesting to trace the connection between the proliferation of the web over wifi and transformation of cafes into places of study. University libraries used to have a monopoly on high quality information and were in a position to dictate to students the "no food or drink" rule. Normally, a student would face a trade-off b/w access to information and food/drink (enjoyment). A combination of web over wifi and cafe let her have the best of both worlds. Schematically, we went from a product to a disjoint union.
