So the blame is on the people?
Quote: "Tony Best, Sense's CEO, said that the blocking factor is that most people simply don't know how to communicate with someone who is both deaf and blind."
So, apparently it is not that the lack of two of the most important senses prevent them from properly experiencing and interacting with the world around them, but that the world around them irrationally insists on a dependance on all human senses for its appreciation.
Though I agree that expanding one's horizons in order to communicate with the deaf-blind is never a bad idea, proposing that the perception of their inability to function properly in our world is false because it is the world that is not properly adapted to their state, is a bit of a stretch.
