I almost added humor as a topic for this video too, because the video is full of humor, in the ways Sabine Hossenfelder depairs while objecting to an unrealisitic understanding of Vacuum Energy.
There is math - Einstein's Field Equation, which is how she proves her point. However she does a good job of explaining the relationships of all the variables, so it is not necessarily intimidating math. And as a result she provides clarity about Vacuum Energy which some of the "new kids on the block" in the field have been researching - thus creating some progress in theoretical physics research.
