I think those old TUI systems are analogous to learning Vim. At first, you don't wtf is going on. But, the more time you spend with it, the more it's ingrained, and eventually becomes second nature.

I've seen many of these systems over the years. Before I moved into software full time, the company I was working for was transitioning from a TUI to a GUI based system. The long time sales and warehousing staff absolutely hated it. Which, yes, is par for the course with any new system. But, I really believe there is an (potential) efficiency to a TUI system that makes it superior to a GUI when dealing with prototypical business operations (order entry, inventory lookup, etc).

Which makes me think, is there a market for "modern" TUI systems?
