It also seems like most modern UX theory values discoverability and ease-of-first-time-use far more than ergonomics for everyday users. At my work the UX/design team often evaluate new features by putting people in front of them without telling them anything and expecting them to work everything out on their own (often while they're being watched). A lot of our product is something that our customers interact with many times per day, yet we don't spend 1% the time optimizing workflows for the people who know what's going on compared to what we do for first time users.
