The one-size-fits-all mistake.
For twenty years, the AAC industry has been built on one idea: every communicator
should learn the same board, designed by the company, and nobody should change it.
The newest apps take it to the end of the line: a board you can't
customize. Same words, same places, same pictures, for every child on earth.
Ask any parent of a child with special needs how well "the same for everyone" has
worked out for them. Schools, doctors, therapies, forms: all of it built for an average
child who doesn't exist.
AAC should be the one place that's different. It's your child's voice.
