It seems a little over-the-top to be angry at physicists from 30-40 years ago for being wrong.
Scientists aren’t priests, and science isn’t a religion. Expecting scientists to always be right, always be humble, and everything they add to “science” to be sacred and correct and immutable is a little silly.
This is how science works. It’s messy. It goes in delicious looking directions that turn out to be dead ends. Humans create ideas (with all the hubris and errors of being human) that other humans test (with all the hubris and errors of being human.)
I was struck by how angered she was by physicists thinking they were right and saying “we’re doing something real”. They were doing something real: they were exploring and testing an idea. Without that work, the idea could never have been proved wrong.
(My personal “string theory” is that string/cordage is humanity’s greatest invention, and my user name is a joke.)
