Sure, but writing in Markdown isn't how humans write either.
Markdown is the least bad way for humans to write, IME. It definitely beats handwriting, it definitely beats every other markup/formatting language, and subjectively I find it nicer than MS Word style "WYSIWYG" formatting although that part is maybe more arguable.
This, combined with git forges pages concept or tilde user accounts makes for nice corners in the webs.
