Mostly, I like this article. But... :
"This is the same phenomenon you see with defense contractors or fashion brands. The dumber the customers, the more effort you expend on the process of selling things to them rather than making the things you sell."
At first I thought this was funny and smart... but now I think it's rather glib. "Fashion brands" is almost by definition entirely a marketing exercise... tautology is a pretty boring type of argument. Now... the industry in wearable items is huge and not entirely oriented around marketing at the expense of value...
Defence contracting... I think it's a lot more complicated than dumb customers. For one, there are only a few customers... typically governments. So in a market with a low ratio of buyers to sellers, clearly you have to invest a lot in getting attention. And given the nature of contracts, once you have their attention (and their contract), the profit motive is then to satisfy the contract as close to the line as possible... that is... to skimp and make your product as crap as you can get away with.
Witty insights should really have some grounding in reality, and point the way to other interesting thoughts. This just seems to be a collective geek snigger at the aggressive and the fashionable.
