To me, this is the difference between a "good enough" theory vs. a "totally flawed" theory. Obviously, there's a gray area between the two, but I think the distinction is valid. We had a working model of electricity that was good enough for some initial applications. Contrast with, say, Lysenkoism in Russia, which was totally flawed.

BTW, I never said we were at an apex of knowledge. I'm trying to quell the concern that what little we do know is somehow going to turn to mud one day. That's very unlikely.
