You're right. When I wrote the above, what I had in mind was sculpture (what I've mostly see consumer 3D printers making these days - representational things like D&D set pieces, or cosplay props). The interface of programs like Maya, for making very complex 3D shapes, I wouldn't call trivial.
But in hindsight the context of the discussion is more about industrial design of functional consumer goods, which I completely agree is a highly skilled trade, and while learning the CAD program is still a lot of work, that's one of the least of the requirements.
