Rewriting from scratch is usually the only way to replace core data structures, which is the *only* thing that matters in any piece of code.
Things that bad programmers believe: incremental refactoring is preferable to rewriting. Nope.

@fchollet very few businesses can support a complete rewrite of their supporting software though -
@mat_kelcey right, it's not always something you can afford. Unless you do it frequently, in which case your codebase will be kept small. - Show replies

Let's point out that Google does rewrite systems from scratch: one example is TensorFlow, which replaces a legacy distributed NN framework.

Upgrading the legacy system would have been insane; TF is brilliant and paves the way for the future. Long-term thinking.
