That's just an opinion, not an argument. It adds nothing valuable to this discussion. If you want to criticize, can you point to specific things and explain your reasoning? It might be useful, to make an actual point. Or whatever.
It's interesting but I wouldn't use it, partly because I got some hand functions still as a quadriplegic, I'm typing this on a keyboard with only my thumbs and I can type quite fast. I also have my mouse clicks switched as I cannot move my index finger, so I click with my middle finger. Other quadriplegics have it worse so things like this would be dope for them. At the end of the day, we will adapt to anything regardless.
I'm in the process of doing this free for someone I know. I got into it clueless to how any of this works and what it may cost. Reading you post $10,000 minimum and researching a few days ago on how much book editors get paid (and exactly how) slightly shocked me!
