Voice recognition should be fine in no time at all.

It's not just about dictating text and having the computer type it. That's going to be reasonably fast, once one has the computer "trained" to recognize one's voice.

However, there are many things one can do on a computer via mouse and/or keyboard in much less time than it would take you to tell the computer how to do it using your voice. Various CAD and desktop publishing applications come to mind.

And even if all we're talking about is dictating documents: Not everybody can dictate a coherent document. Different people have different preferred communication "channels". Some people simply cannot collect and deliver their thoughts in a clear manner by speaking; they can only achieve that kind of clarity and organization by writing. I'm not talking about the mechanics of speech, I'm talking about what goes on in one's brain as we marshall our thoughts and prepare to send them out via speech or writing. Those are two different kinds of thought processes, and in most people, one of them works better than the other.

And as I always say, hundreds of people talking to their computers in a cube farm isn't going to work.

Voice recognition is never going to work as an all-purpose interface for a computer, just as the mouse won't work as an all-purpose interface for a computer (no matter how much Steve Jobs wanted it to), touch-screen won't work as an all-purpose interface for a computer, just as typing won't work as an all-purpose interface for a computer (command line fanbois back off; try doing CAD or photo editing with a command line).

That being said, the keyboard/mouse combination remains the most efficient human/machine interface overall for a general-purpose computing machine. To the extent that we devolve into using many different special-purpose computing machines for specific purposes, all bets are off.

But composing big documents and swatches of code will remain a very important purpose for the use of computing machines, and the keyboard will always be the most efficient way to do that.
