Sketchup is Sketchup because Google's motive for buying it had nothing to do with design. Google bought Sketchup (and gives it away) so that people would draft up their house or a famous building or their car or whatever and then geotag it. Thus, Google has a massive crowdsourced database of the world in 3D. This greatly improves their machine learning and allows them to better model 3D from various 2D data sources. Sketchup Pro is the program they bought and still sell. If you want to do models of your furniture to put on the Sketchup Warehouse, you need Pro. You can get on there and find every piece of furniture Ikea has ever put out. And you can build your kitchen without ever swinging a hammer - it's cool. But it also means that "designers" aren't using big boy tools anymore. I think I read about minimalism on here not a week ago. The argument was that minimalism isn't a design aesthetic, it's the end result of perfecting something.
