There are many kinds of disabilities out there.
I suffer from a few cognitive issues that make even my native language difficult to write without the aid of something like ProWritingAid.
But my youngest daughter suffers from intellectual disabilities and has a functional English level of that of 5th grader.
Without the embedded nature of AI, especially generative AI, which offers a person words for text messages, her language skills would be poor at a best. The same technology is employed in her talking device, allowing her to speak to others because of a speech impediment.
She isn’t inclined to write a novel at this time, but she shouldn’t be denied the ability to use generative AI to craft a novel from her own ideas. Nor should anyone with such limitations be denied access to such technologies because it’s seen as cheating.
My daughter’s writing disability is very real indeed, and generative AI can provide her a window into the world she would normally be denied.
I’m sorry others in the disability writing community may not feel AI is needed for them, but I can see the benefits for some form of disabilities.
