Is Machine Learning The Solution to Web Accessibility?

I was traveling last fall with my boss, and we began to talk about our upcoming conference day around artificial intelligence. We came to the topic of machine learning, and I mentioned, half jokingly, that theoretically all web accessibility barriers could be automatically resolved through the proper application of machine learning. Since that day I've continued to consider the challenge, and have come across a few articles that have reinforced the theory. As our Q1 conference day is soon coming, I've decided to take a few minutes to share my thoughts. For those who don't know, web accessibility is the practice of making content and applications ("web content") accessible to those with a variety of disabilities, "...including blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, limited movement, speech disabilities, [and] photosensitivity" (https://www.w3.org/TR/WCAG20/).
