I'm building an EMR and there is a large portion that is CRUD, but that doesn't mean I don't rely on enormous forms or don't need client-side validation.

My personal suspicion is that most providers would ultimately prefer a well-designed TUI from 1995 to a fancy SPA that stops working whenever the Wi-Fi is slow (i.e. most days).

Offline mode exists for SPAs. And TUIs aren't realistic because the nurses use Ipads.
