These people exist, and always have, regardless of the technology.  It was great reading it to be reminded that the people I work with really aren't unique.

I have found these same people also hang around government, or at least municipal government where I have some experience as an elected official.  They come to meetings and imply very clearly we are either slow or stupid and tend to talk to us loudly as if we can't hear very well.  They then go on to point out just how we should do our jobs (to their benefit of course) as if we hadn't already understood all of that several years ago but for financial reasons simply could not implement.
