Modern TUI frameworks break terminal accessibility by replacing linear text streams with spatial layouts

Modern TUI frameworks like Ink, Bubble Tea, and tcell render interfaces as 2D spatial grids rather than linear text streams, causing screen readers to malfunction and making terminal applications less accessible than properly designed graphical UIs.
Engineers building CLI tools with modern TUI frameworks may be creating interfaces that are less accessible than graphical alternatives, despite the widespread assumption that text-based interfaces are automatically accessible. The accessibility failure stems from frameworks abandoning the terminal's linear text stream model in favor of spatial layouts that screen readers cannot parse.

Modern TUI frameworks render interfaces as 2D spatial grids rather than linear text streams, causing screen readers to lose track of content as the cursor jumps unpredictably with each screen update.
Older terminal applications like Irssi used VT100 scrolling regions and maintained the terminal's linear data flow, making them more accessible to screen readers than modern TUIs.
Properly designed graphical UIs provide nested structures with metadata that screen readers can parse, making them potentially more accessible than modern TUIs despite the common assumption that text interfaces are inherently accessible.
