The most surprising thing is there might be any correlation between performance of top end search engines at such widely divergent areas of human experience, low quantity weird software errors and high quantity pointless hollywood blather. Certainly a junky demo search engine could be beaten all around by any top end search engine. But I'm surprised at the top end they are competitive in both areas.

It would be like finding out olympic class weight lifters tend to also be olympic class marathon runners. Or the best commuter vehicle and best 100 ton mining truck happen to be the same vehicle.
