It be nice if content and typesetting can be completely separated, where I just write content, and something (LaTeX, AI, some manual typesetter) does all the typesetting.
Also, should I be the one controlling how the reader consume my content? Maybe the reader prefers another font? Or the reader is viewing in a kindle so pdf page size should be different?
This would be impossible unless the reader have my LaTeX source code and compile it themselves. But it is super simple for epub, or html webpage (by modifying the css).
