I haven't yet -- I work slowly, so I'm still thinking about the transfer of authority from authors to systems, and the increasing opacity of those systems to direct interpretation. We all know, for example, that Google "works", in that the results feel better than the competition, but not only can we not offer any real interpretation of _why_ it works, neither can anyone on Google's staff.

There is human intelligence behind the search engine, of course, but it is made unintelligible by the scale and complexity of the algorithm. (This is analogous to the inability of analysts to offer convincing accounts of _why_ IBM is trading at $147.22 as I type this.)

So I'll write more about it, but only after I have more to say in a way that makes sense to me.
