I don't think I agree. If a model is known to be largely false but in certain situations it provides good enough results and is easy to work with, that model will continue to get used until a better one replaces it. It's the classic problem undergrads have with Physics I vs. Physics II where the second declares all of Physics I false. Really, it's that Physics II is more accurate under more conditions, but that doesn't make what's learned in Physics I useless.
