Plus, with Latex you can use LLMs as assistants and they do a great job thanks to so much Latex data they've seen in training.

And at least I can be sure that any math expression can be written somehow in latex, no mater how bizarre.

Outdated means there is something better that is now used to substitute an old technology, which is not the case for Latex. Unfortunately, programmers tend to think "outdated" just means "was created more than 5 years ago"...
