Indeed, some of our main concerns are about user speed. We also know some concrete use cases where 3 decades old systems are still in place because none of the previous attempts at modernizing the application were able to allow for even half of the speed -- and, in one of those use cases, user speed was really, really mandatory. When I talk about those cases, people usually argue that those systems are being used by "old farts" who will always resist to the change. However, it's really interesting to notice that even the younger users prefer those old systems because of their reliability and speed. Overall, I think there's a huge misunderstanding about UX. I mean, things like Material Design animations and icons are nice but, in business applications, users want simply to query/input their stuff from/into the system and leave and go to do the rest of their jobs. They don't want to feel "pleased", they don't want to "experience" the software. The software should operate as an extension of their minds and they don't even want to realize they are using it.
