When Mazulu says GR jobs will be cut he is referring to Goat Roper jobs. The job of tying a goat with a rope is when physically straining, thus his mentioning of a "physics job". Here a young goat is resisting the work of a professional Goat Roaper physicalist.
As the theoriy of General Relativity says the Goat Roper accelerating the goat using the rope around himself close to speed of light, if such is deemed possible, will inevitably create a frame dragging effect which will drag the goat in a gravitational sinkhole towards the Goat Roper...
