Doubly so if it's a stenotype (typist?).
How many people know steno? No one you know, but hey that's how we chew the fat on the Internet. How many of the 7 billion people can type?
People already effectively use dictation. John Siracusa used Dragon to write his 20,000 word Mac OS reviews:

David Pogue has been using dictation for years:
Software developers have even cobbled together voice programming solutions:

Also, let me throw out my standard response: "No one said..." that you have to use a keyboard or voice dictation, you have the option of using both solutions.
People don't always want to simply type fast. Imagine other use case cases, like designers, for example. They might be using a Wacom tablet and need to reach for the keyboard to "create a new layer", "change font to San Francisco", "50x100 rectangle", etc. Wouldn't voice recognition be much easier?
Here's an interesting study on chorded keyboards:
That case study interests me, but it really glazes over stenotype and palantype. I'll email Bill and see if I can get a discussion going. Cheers
