While I understand that the title was chosen to be short and snappy, "Accessibility of machine learning and generative AI" doesn't quite reflect what the note is about.

Machine learning and GenAI are high level technologies, and there's no intrinsic "accessibility" aspect to them.

What the note tries to cover is how machine learning and GenAI can help generate output - as either a remediation for end users, or as an aid during development - that can help increase the accessibility of content.

So, while less exciting, something more along the lines of "The use of machine learning and generative AI to create accessible content" or similar.
