Supercomputer or not, it's a terminal.

In the real-CRT-terminal days of the 1970's & 1980's of course the interface to the local or remote mainframe or PC was IO-bound but not much else could slow it down.

UI elements like the keyboard/screen combo have been expected to perform at the speed of light for decades using only simple hardware to begin with.

The UX of a modern terminal app would best be not much different than a real CRT unit unless the traditional keyboard/display UI could actually be improved in some way.

Even adding a "mouse" didn't slow down the Atari 400 (which was only an 8-bit personal computer) when I programmed it to use the gaming trackball to point & click plus drag & drop. That was using regular Atari Basic, no assembly code. And I'm no software engineer.

A decade later once the mouse had been recognized and brought into the mainstream it didn't seem to slow down DOS at all, compared to a rodent-free environment.

Using modern electronics surely there should not be any perceptable lag compared to non-intelligent CRT's over dial-up.

Unless maybe the engineers are not as advanced as they used to be decades ago.

Or maybe the management/approach is faulty, all it takes is one non-leader in a leadership position to negate the abilities of all talented operators working under that sub-hierarchy.
