Picking from 100 options is what the mouse is best for. Keyboards require learning so they are best for the options you do often enough to learn. I know about 10 different vi commands of the hundreds.
There is more than selecting options. Selecting text is normally better with a mouse.
>Keyboards require learning
We are not talking about keyboard shortcuts (key combinations that you press to do something) by the way, and about the actual typing of commands in the terminal/shell/repl what ever...
Quite the opposite, my argument is that habits are changeable.
> Fundamentally a computer is something that execute instructions. It is pretty poor interface to pick instructions from 100 options using a mouse as opposed to type it using a keyboard. A mouse hides the power of the computer behind a set of fixed clickable options. That is a pretty poor interface.
You continue to argue for my point. OP was claiming that measured efficiency does not matter because it's about "flow". I argue that one can teach oneself to flow differently, the commands can be learned.
