Correletion; smart people have sometimes already progressed so much they don't have to do everything as fast as possible to get more accomplished than the frantic operators.
>1. You aren't smart.
Very likely for most people, depending on where you draw the line(s). But you could very well still be brilliant.
>2. . . . can't easily learn touch typing.
OTOH could already have learned touch typing, and recognized the advantages for stream-of-consciousness storytelling, but moved forward without it when it comes to typing in code.
>3. For some reason you rarely have to type in your life.
But when you do, you want to stop and make sure it is exactly as expected every time before you hit "enter".
