LaTeX is obviously a standard for scientific and maths publishing; but on the whole it's a rather, ahem, 1980s technology. Technology is moving forward, except for retro-fetishists (& okay, I still use vi :-).
While it is 1980's technology, the computer industry hasn't really come up with anything in the last 20 years better than what we had back then. Technology hasn't moved forward, rather, it has in many cases moved painfully backwards.
