Is it possible that unifying efforts of QFT and gravity are futile because during the 13.8 billion years either gravity or quantum fields or both 'lost' some of their properties that would give us a clue if we could still measure or calculate?

One scientist says. the interaction of a particle with a quantum field is like skating on ice when you dive in, you interact so that you have mass. What came first? Does the object have mass first and then react, or does it react and then gain mass?
