This has been an interesting thing for me to watch as it's such a case of people having widely different experiences. I'm sure people that didn't grow up on a keyboard like me can probably talk quicker than they type, but even aside from me being a fairly good typist my speech is held up by being a bit more halting, a bit more of backtracking on word choice, sometimes not quite the same 'voice' of writing as I'm aiming for, all of which obliterates any speed advantage it'd have for me.

But happy to see people get more options.

This reminds me of Eternity's End by Jeffrey Carver and the implants they had. Released in 2000 but the more time goes on the more the neural implant technology is coming about. To be fair I think Enders Game had similar tech to detect subvocal speech like this product.

Writing also filters the useless crap that is spoken but is not worth writing down.
