I think this is true, if we also allow that people who have been using the UI for a while also aren't confused and overwhelmed by it.

So the whole UI is being optimised for non-technical new users. Which does make sense commercially - you don't want your product reviews all about how the UI is too complex. But it would be nice to be able to flip a switch and tell the thing "I know what I'm doing now, can I have my pixels back please?"
