I think she's been bazinga brained since long before Elon, he just really exacerbated it. But the seeds of bazinga were certainly there before. In 2015, 3 years before getting with Musk, she said she wasn't a feminist. Also she made a Dune concept album in 2010 with, as far as I can tell, no realization that it's a cautionary tale and not just an epic space opera.
