It may be mathematically convenient to treat gravity as being a field like electromagnetism, but it isn’t physically real. Is that correct?

I always wonder why physicists in popular science media treat it as such a big deal that gravity is “so much weaker” than the other forces, when gravity isn’t really a force. If gravity isn’t a force, then why compare its strength to other true forces, then act surprised?

But if this experiment offers additional evidence that gravity is quantized, then it simply means that spacetime itself is quantized (gravity isn’t a force). Is that correct?
