I’ve never heard String Theory referred to as nonsense. I know Loop Theory is now in the debate. I haven’t delved too deeply into the mix, so I’m just on the sideline.
I don’t think she’s saying String Theory is nonsense, just Dark Dimensions and naturalness.

Once upon a time, string theory was interesting...
However, it turned out to be “non-testable”...
String theory eventually morphed (to save jobs) into super-string theory...
Super string theory is utter nonsense...
Even a close examination of the filter in your clothes dryer will support that conclusion...
