Said a different way, if you believe in the fine-tuned universe theory, then the multiverse theory would by definition predict our own outcome. It doesn't make either true, rather one of many puzzle pieces that happen to fit together. In 200 years, we may have proof of gravitational waves (or have found none) and many other interesting puzzle pieces that will continue to drive the thinking within quantum mechanics and string theory. Some believe the entire branch of string theory to be philosophy -- though I think this is limited by the belief that because we can't test many of these theories today that we will never find a way to test them in the future.
