For a work app doing data entry, there is supposed to be training for users, because it's somebody's job to use the program consistently all the time everyday.

I would agree with you if we were talking about a customer facing webpage or something. But an app for say an accountant? That should be a TUI or as fast as a TUI. The workers are literally hired to get over the learning curve and become fast with the app, so it's not as big a concern if first-use is more difficult. You arent trying to sell them a product and drive higher percentage click through.

I 100% agree with you for applications for say online shopping. Those should prioritize new user experience over long time user efficiency probably.
