I sometimes think that these days, anyone able to focus long enough on one subject to read a posting like yours will be classified as having some form of autism. Maybe we'll see the day that people who are able to read and digest a 1200-page history book will be diagnosed and locked up for their own safety.

At the extremes, autism is a disability of sorts, of course, but the "spectrum" has been stretched to include just about anybody, as if individual differences aren't supposed to exist, ignoring the fact that few things get designed and built without some engineer somewhere going into "autistic mode" for a while.
