I'm glad this helps people with paralysis, but I can't help seeing the sci-fi dystopian side of tech like this.
What if some people are forced to have their inner thoughts decoded against their will? It sounds like just the thing some authoritarian thought police would use to root out their enemies.
Does that sound far-fetched? I'm sure if it were suggested as an upgrade to existing lie-detecting polygraph tests, lots of people would approve. Slippery slope.
