Not only developers, but I’ve read a research where a POS system was upgraded from a TUI to a GUI, and while new hires enjoyed the new system, experienced ones disliked due to the reduced performance.

There is also an old research showing that a small delay in the response time has a big impact on the productivity [1]. The keyboard only interface and high performance/low latency can be an excellent choice for power users/users who care about productivity.

In theory we can have all that using regular GUIs, but almost no developer/UX cares about this today. The TUI constraints ends up being an advantage for getting things done in some situations.

The Economic Value of Rapid Response Time https://jlelliotton.blogspot.com/p/the-economic-value-of-rap...



Of course we're now losing the rapid response time in terminals too because we need to buffer everything to make sure it's painted perfectly. That people think GPU acceleration is a good idea in a terminal has left me not only baffled but depressed for the future of a technology that was too lame to ruin (until recently). But here we are.
