Yes, true. Picking winners is a hard game though... so I have sympathy for that part.
The part that bothers me is crapping on other fields for things we would tolerate, even respect in our own. If a tech company was messing with 3d printing experimentally, released some esoteric and impractical new database alternative or somesuch... We might criticise, but this reaction to experimental architecture is extreme.
I think a lot of it is the artsy language used by architects. It triggers HNers. Meanwhile, we appreciate abstract takes by pg, Stallman, or whatnot.
Consider: "Free software is software that respects your freedom and the social solidarity of your community" - Stallman. This is OK to us, even though it probably sounds like meaningless ideological rambling to the uninitiated.
Meanwhile: "The aesthetics of this house are the result of a technical and material effort, it was not an aesthetic approach only. It is an honest form, a sincere form.” is intolerable to many the HN community. The base assumption is that the emperor has no clothes and regicide is the only solution.
