"Creating garbage is easy now."

It runs poorly, loses keystrokes, and easily gets bogged down with too much terminal input.

I don't want candy coated monospace ASCII graphics. I want something fast and functional. The graphics are _entirely_ secondary. You've missed the point of what a TUI is.

Terminals still have poor keyboard support these days, starting with the Escape key (which should not be ASCII 27 IMO) and various ctrl/shift/alt... key combinations.
