I wholeheartedly agree. Making automatic alt-text available for those types of posts would go a long way in addressing the accessibility issues that plague image posts on Twitter. Their current UX for adding alt-text is painful and content authors are unlikely to use it... Seems like a great place for automation/OCR

If the OCR is good enough to deal with these text posts, isn't it already built into screen reading software that would make the alt-text duplication unnecessary?

Not if you’re on a smartphone. This is one of the problems with mobile — no way to have one app interact with another. Many people with disabilities rely on this sort of functionality on desktop and cannot use it on mobile. The only accessibility features that exist are the ones the OS implements.
