What are TUIs and why now?

Text User Interfaces — full-screen terminal apps. Surging because AI agents live in shells, modern tools prettify output, emulators render like GPUs.

How do I start designing TUIs?

Master seven layouts: multi-panel, stacked lists, etc. Obsess over cells. Use Base16 colors, Unicode components. Build in Ratatui or Bubble Tea.

Will TUIs replace IDEs?

Not fully — but hybrid. Agents handle grunt, TUIs orchestrate. Expect terminal-first dev by 2026.
