MathML vs LaTeX

I use LaTeX. I tried with MathML, but which MathML? Is it presentational or
semantic?
The fact is that mathematicians use LaTeX. It is a language that can
separate content from presentation. It is more syntactically concise. It
looks like math. People with cannot author with LaTeX can use other
products like Word to formulate mathematics, and that can be parsed into
LaTeX.
First, I must express my gratitude for the members of W3C who tried to
develop an alternative to LaTeX, but they did not succeed. LaTeX is so much
easier to code. There is no need to think about a presentational or
semantic form. I think it is time to drop MathML, as much as I love sematic
MathML and the people who developed it.
