I'm not convinced, because all a keyboard really costs you is latency, while almost every human-machine interaction is actually bandwidth limited (by human output).

Even getting zero latency from a perfect brain-machine interface would not make you meaningfully faster at most things I'd assume.

Yeah I noticed this as I became a faster typer. I very often find myself 'buffering' on choosing the right words / code more than I do on my typing speed.
