For years we wanted to do digital publishing and the technology came and it was good. Then the idea of a beautiful manuscript also came to light and that was good, too. We wrote with pencils, pens, crayons and typewriters. Then the word processor crept in and the idea of writing once and then editing became available. So then became the distractions of digital media.
We used to publish with Xerox machines and we learned the lessons of how it must be a direct run with beautifully edited plates. Otherwise the second run of the first run would look like garbage. Again the digital media beckoned.
Even the old idea of verbal to text was selling and still it was not as good as typing. Now we are feeling the push of the "Artificial Intelligence" and it is soulless and gutless. The memes are funny but that is the composition in text.
The digital reader is a very good thing but it must be flow-able text. The PDF is not a good tool for digital reading as it is dependent on the original composition and layout and the canvas is not the destination.
