MathML was created as a human-readable interchange format. It was never intended to be written by humans. Much like how HTML is often generated from markdown nowadays.

It was specifically created to avoid TeX being used on the web, because TeX is ill-defined, loosely structured and lacks basic functionality such as Unicode support.

MathML is not human-readable as shown by the example in the wikipedia link, and TeX is supposed to have Unicode support these days, assuming you have a properly configured modern system, that's not a good example.
