LaTeX, and TeX, are the last gasp of a long line of development. That line starts with MIT's RUNOFF, which begat roff, nroff ("New ROFF"), troff, ditroff, psroff, and finally TeX. It's the last of the programming-language like word processing systems.
TeX assumes your final output is paper. That's an obsolete assumption. The math features are concerned with presentation. You can't cut a formula from TeX and paste it into Mathematica or MathCAD and have it understood. TeX doesn't understand mathematical notation; it just format it for printing.

We need to get past that.
