Conclusion

₆₉

XML & MathML are assembly-level languages for the WWW
LaTeX and TeX are not perfect, but they are great tools for working with hypertext
- LaTeX: human-friendly character-based interface for authoring content
- TeX: back-end interface for getting print-oriented output
While far from being complete and polished, much of the needed machinery is already available
Wish list: more coordinated work within the (La)TeX community (see W3C)

LaTeX is established and boring by now. XML is still young and challenging. They are two powerful complementary technologies. Cheer up the old one, and have fun with the new one.
