This makes sense. Development velocity is bought by having a short product life with few users. As you gain users that depend on your product, velocity must drop by definition.

The reason for this is that product development involves making decisions which can later be classified as good or bad decisions.

The good decisions must remain stable, while the bad decisions must remain open to change and therefore remain unstable.

The AI doesn't know anything about the user experience, which means it will inevitably change the good decisions as well.
