You're entitled to your opinion but this will open up a world of possibilities to people who couldn't work in these fields previously due to their own non-dyslexia disability. Handless intelligent people shouldn't lose out because incumbents don't want to share their lane.
The AI we have today has very little to do with writing prompts, you still need to understand, correct, glue and edit the results and that is most of the work so you still need skilled professionals.
Pretty much everythnig I see about using AI is based around the construction of proper prompts to achieve the type of output you require.
Could you explain how prompts are not a big part of interrfacing with AI?
Yes but you are trading off a lot of people with a one kind of disadvantage, dyslexia, for the benefit of very very few people with a motor skills disability that affects their ability to draw or manipulate an input device which is a different disadvantage. What's the acceptable ratio? One handless person enabled for every 100,000 dyslexics sidelined? Is that fair? How do you work out an acceptable tradeoff?
It is not a given that everyone can or should be enabled to do everything possible at any cost; people in wheelchairs can't be firefighters and we don't make all old subway lines fully accessible because it is incredibly expensive.
Disadvantaging a huge number of people for the benefit of very few has a societal cost.
