With markup converters like Pandoc, it is now possible to generate LaTeX documents without ever touching any LaTeX code.
However, obtaining aesthetic page breaks for slightly complex documents, taking for example into account figures, widows and orphans may still require manual intervention in the LaTeX code. (I know there are packages for this out there, but unfortunately they do not resolve all issues.)
So it seems that we are quite not yet at that utopian point were one can blindly write content without ever having to worry about how the output will look like. (This argument is often used though for LaTeX/LyX advocacy.)
This made me wonder: Did LaTeX 2ε developers intend for unattended typesetting? If not, will LaTeX 3 change anything with respect to this?
For the sake of clarity, I am mainly referring to documents such as dissertations, reports and books.
