I just watched an impressive TED talk. Essentially, he addresses the pictures that autistic people use to communicate what they want. He talks about how pictures are much more concrete than language. Then, he finds a way to use those concrete pictures to form completely coherent sentences in English (or any language).

At 8:30, he talks about learning languages as a child vs. an adult. His app uses the same part of the brain as WAYK to learn languages without going through your mother tongue.
I love the emphasis on TQ: Obvious
