She explains it nicely. She mentions "Quantum Mechanics" several times, physicsts like to talk about these tehories as if they were a single intelligible theory, but they are not, there are as many Quantum Mechanics as there are physicsts. At the end of the talk she mentions an experiment, but in physics the meaning of the word "experiment" has changed too, if the experiment contradicts existing Quantum Mechanics, physicists will simply create a new flavor of it.
