I think there's a very strong analogy between the Copernican model vs Ptolemaic and computer languages (for example) - you can have something like C which has obvious defects (grant this for the argument, substitute something else if you like), but a replacement like Rust isn't taking on just C, but the entire ecosystem around C and all the tooling and knowledge therein.

Similarly the Copernican model was "more correct" depending on how you look at it (currently we model everything relative to everything else, the earth and sun "orbit" around a midpoint that is inside the surface of the sun but not the exact center, for example) but it provided WORSE predictions than the Ptolemaic model of the time.

And this had real practical implications in the technology of the day - navigation charts, etc, analogous to trying to use new tooling and finding it doesn't support aspects the old tooling did.
