My biggest issue with PDF it's hard to read on screens. On top of that PDF forms are notoriously buggy, tables are almost impossible to machine-read without specialized software, and even copy-pasting can be a hassle.
I get that print will continue to be a thing to some extent, but I don't think that business or government documents need to be typeset with static pages. I think it's time we move on to a much simpler standard that is made for free-flowing text.
PDF has also been problematic as a standard format, since it referred to proprietary features up until 2023.
