And Newtonian gravity works
very, very well indeed: for many purposes one can dispense with the fiddliness of GR and stick with Newton.
If you believe that science's job is to tell us what the Universe
really does, then you're going to go with GR as our current best approximation to the truth. If you believe that science's job is to make useful predictions about the behaviour of the Universe, then you'll pick whichever tool is best suited (in ease and accuracy) to the job at hand.
