Assistive technology keeps growing and improving, though. These days most operating systems already come with a voice control feature, designed for people with a motor impairment to use their device entirely by voice. When you add alt text to an image button, you're not just enabling a blind user to hear a description, you're also enabling someone with carpal tunnel to speak the name of that button to activate it. Most other accessibility APIs and preferences have multiple use cases like that, too. That's why accessibility is designed the way it is: you're not modifying your app to work with specific disabilities, you're adding missing semantics and respecting user accessibility preferences, and assistive technology adapts things to work with different users.
