Complexity comes gradually. You will not find reasonable to reparse HTML spit out from Dreamweaver or Word to fit js/cgi parts in there but withstanding 5 years of work you may find perfectly sane to compile JSX. Plus most of the people in the field never wanted to mantain two very different stacks for work and play, it's also a good way to dogfood. Also you can recover better in plain text when markup is messed up vs a wysiwyg editor.
