The Mouse Is a Design Flaw

Six months of terminal-only work changed how I think about every interface I build.

I spent two weeks last January moving daily work into the terminal — email triage, file management, notes, and music. It was not productivity theater. I wanted to see what happened when the mouse no longer interrupted every task.

The Latency Tax

Each time your hand leaves the keyboard for the mouse, you lose a small delay. Multiply that across hundreds of context switches and the session stops feeling continuous. The terminal keeps the loop tight: keystrokes in, result out, eyes forward.

Composability Beats Features

GUI applications give you controls. The terminal gives you building blocks. A pipeline of grep, sed, and awk can replace hours of manual spreadsheet work. Once tools speak plain text, graphical interfaces start to look like tradeoffs instead of defaults.

“The best interface is the one your hands remember.”
