I used to think this, but interestingly, after learning several other CAD platforms, you realize both how limited SketchUp is and how the usability is really not substantially different with the huge exception of the onboarding experience. (Not to even get in to what garbage geometry it barfs out.) There is a traditional UI paradigm in the CAD world which is totally divorced from the desktop UI world that's become ubiquitous in the past few decades. SketchUp was succesful mostly because it rethought all that based on what laymen are familiar with. But Especially at it's absurd new price-point, I think the argument for SketchUp's existence would go away entirely if Rhino just added a waaaaay simplified default workspace, enabled a sensible set of snapping options and the gumball by default, and maybe added a handful of contextual cues for common manipulation tools.
