> Really it shouldn't be up to the developer it should be up to the disabled person to buy tools. Just like someone may need to buy a wheelchair to move around, they should have to buy a specialty browser that handles their limited visibility needs or brail tool interface.
How can buying a specialty browser solve a problem of a blind person needing alt text for images?
You, as a developer, can determine when AI-generated text is good enough for your images—sometimes it is, and sometimes it isn't. A specialty browser cannot, and should not, be trusted to make that decision, so it will need hints from the developer. And, once the developer offers those hints, any mainstream browser, not just specialty products, can make use of them.
