Gravity isn’t a force. It’s the curvature of spacetime, the bending itself. You can’t compare it to the three other forces.

I do agree but, it is very common in academia to disagree with this, to believe that the geometric representation of gravity is merely a clever trick to approximate gravitational effects, but that in reality it is caused by a force-carrying particle just like any other force, a graviton, and spacetime is flat. That was the basis of String Theory and some other views. I don't know why this view is so popular but it is.
