This just got linked to by the Y combinator news account, without proper context,
so a brief introduction: A month ago (end of May / early June 2014) I had a
Twitter conversation with a bunch of acquaintances. One tweet in the middle
of that thread, with obligatory hyperbole, was me saying that I think VR is
bad news.

Well, that part of the thread (but not the rest that provides context) recently
got retweeted, and then someone asked me if I could explain what I mean by that,
and because Twitter is a great platform for delivering 140 character slogans and
not so great for lengthy explanations, I wrote this. So, obligatory disclaimer:
