More people are keeping their files digital and don't intend to print. It's preferable that we simply share links to a webpage or cloud document that is meant to be scrolled through.. but many professionals still insist on emailing file attachments because they are comfortable creating Word Docs or Google Docs, but have no idea how to create a webpage.
PDFs continue to be the file format of choice for portable documents. Some document editing apps, such as Google Docs, have evolved to allow pageless document view - functioning like an endless scrolling web page or an eBook. Exporting a long document to PDF can be jarring when suddenly important content is interrupted by an awkward page break. It's time for Adobe Acrobat to evolve to allow files to be exported as pageless files, like a continuous scrolling eBook. The most efficient way to navigate this kind of pageless document is with "chapters" indicated by headers (H1, H2 etc). This would also encourage more people to learn the correct heading hierarchy. An emphasized scroll bar should indicate how far along you are in the document. Ideally, the reader should be able to increase font sizes, bookmark sections and add comments. To reduce confusion with PDFs designed for print, you can apply a file extension.PDFx or .PDFd
If Acrobat supported this, it would encourage the most popular document editors to favour designing for screen reading.

Update:
I've been thinking about a better way to backup my files for archiving. I had some issues with Google Docs - ironically the only way to really export them is as a Microsoft Word Doc or PDF... it's difficult to even move files between Google Drives (ownership is not transferable between gmail drive and a google workspace drive without making a copy of every file). If it was a regular file I could easily copy, move or back it up. I am considering moving towards using Markdown for my documentation, since they're small simple text files and the formatting tends to display well whether I need to export it as HTML or as a PDF. I've been sharing Google Docs with colleagues since it's a pageless format and the view is pretty clean, and quick to open and read. They're still confused how to save my document within their own folders. However, since my issues with managing Google Docs, I am considering using a Markdown editor instead. I still need to be able to share my documents with colleagues in an easily accessible format that isn't an actual webpage, so I might be stuck with PDF. I don't want to go back to Microsoft Word because it tends to force paged views when someone else opens the file, among other issues with versions. This is again an opportunity for Adobe to come up with a document system that looks like a scrolling webpage. A portable document that can be shared, browsed using tabs, sections, a TOC etc since almost everybody is already using Adobe Acrobat to open documents, I can see this type of web document being easily adopted.
