@mlevison @cstross @baldur As an alternative to D-K, I'd like to offer the (hypothetical) "celebrity expert syndrome". People who are celebrated for their work in one field tend to be given a licence to exercise their authority in other fields. Some of them then have a big enough ego and little enough self-awareness to actually form prescriptive statements on things they know nothing about. This can become a community trend, too.
I have an example for this from outside tech.
