I haven't tried to make a TUI admittedly, but double buffering is the oldest technique on the planet. A TUI doesn't even need to pay the cost of a lot of pixels since its effective resolution is much lower

Long long time ago, I used to do some graphics stuff in 320x240, which uses a whopping 64KB per buffer, and still has more resolution than a terminal.

In 1GB I could probably fit all the buffers to double-buffer all the TUIs in a whole country. Well, maybe not. But it's likely not that far off.
