One current use is in Airlines Confidential. Ben Baldanza (former CEO of Spirit Airlines) has ALS. He can no longer vocalize well as a result of his disability, and this sort of technology literally gave him back his voice.

I followed a bunch of people. If you're following me back, I don't plan to post here much yet, but you can follow me at @tprophet@defcon.social where I'm (somewhat) more active. Overall I'm not super active on social media anymore--it got boring and repetitive so I changed the channel.

Grabbing my handle over here for now, but I'm most active on defcon dot social. Feel free to follow me over there, and if this place takes off, maybe I'll visit more often. :)
