I see your point, definitely. However, he touches on some very, very evident points about engineers increasingly grabbing design work, employers being OK with it and the results being sh*t.
Im pretty sure it's the other way around
It's "design" stuffing its empty head into everything - webpages that are dozens of MB while effectively being a text document
Applications that are flashy and showy and DONT FUCKING WORK RIGHT
Google maps pretty much have no usability left - i used to be able to use it to navigate across europe,now its a chore to get across town (no options,no waypoints,no route planning - its either do as we say or fuck off)
Id rather have something that isnt shiny but actually does it goddamn job.
And doing more carbon copies of current fad is neither creative or intellectual. Solving problem is,though
I think you're confusing design with decoration. Which is what most engineers do, and why they should keep their hands of it, as well as the Dribbble pixel-pushers which do - as you say - "flashy and showy".
Also then makes it clear that most people calling themselves architect, aren't.
