“These pros and cons can be traced back to one key fact: the PDF representation of a document is fundamentally unstructured.”
PDF is 32 years old and still tells a printer where to put ink. It can’t reflow on a phone, and getting the text out is a chore. Crichton wants a stricter EPUB with no external assets, because Google Docs’ own EPUB export pulls fonts off Google’s servers. Adobe could have fixed PDF decades ago. It sells Acrobat instead.
