Very informative, and I would agree with this. A car dashboard seems complicated when you get into a car, but after you have had lessons, the car is a great tool. Nobody seems to be arguing that the cockpit needs simplification, yet in the computing industry (as you state) everything is dumbed down to etch-a-sketch simplicity for fear of alienating new users.

Mixing consoles also look complicated to a first-time user but I don't think anyone would argue that they need simplification.

Interestingly, Apple News app on the iPad uses cards and a simple layout, yet seems to work well and with no stuttering. This cannot be said for Google+ (and no, I don't want to join communities, stop showing them to me).
