There’s a lot to consider here, and I’m certainly encouraged by Adobe's long standing focus on consistent PDF view experiences. (At least compared to other formats)

That being said, this feels somewhat like Adobe will turn PDFs into a form of markdown where the parser is a (variable?) machine learning algorithm.

Done perfectly, the results could be great. Done badly and the results would be very painful.

Sounds like a way to extend vendor lock-in, as nobody else will be able to implement the same algorithm with any assurance of interoperability.
