It depends on your perspective, since you could similarly argue that it's already here [0] [1].

You can Google "LaTeX templates" and get tons of results; the problem is that most LaTeX templates are terrible, probably because making one that is general-purpose, robust, and gives high-quality output is really hard. But theses are probably one the most common reasons for people to use LaTeX, and there are already hundreds of options available on CTAN [2].

Yeah, but imagine memman.pdf as a Literate .tex source program which had two possible outputs:

- memman.pdf

- memtemplate.tex

where to get the latter one would just iterate through all the possibilities and choose options until one arrived at the end and a template matching the selections which were made was generated.

Maybe a project for the next time I re-read that...
