On the one hand, I think OCR, text to voice, image to text, … has improved quite a lot.
On the other hand more and more stuff is locked away in apps, and javascript blob websites, so I can imagine it’s harder for accessibility tools to access information.
But I’m just guessing. Do any of you know first or second hand?
From my perspective making software, it’s improved. Prior to 2016, I had to be the one pushing WCAG standards. After 2016 it’s been explicit customer facing criteria managed by product managers.
