As a slight tangent, a re-write in another language is also an opportunity for the human engineer to re-design parts of the software that was clunky before or so that in the new target language idioms can be used.

Using automatic tools - whether AI-based or transpilers - leaves that opportunity unused, and both approaches are likely to create some additional technical debt (errors in translation, odd, non-idiomatic ways of doing things introduced by the automatism etc.).
