My humble opinion: it is almost never worth rewriting a large codebase in a new language. The only exceptions are if (a) the old language is so old that it lacks an active community and is no longer being improved, or if (b) the old system needs so many changes that you might as well rewrite it anyway.

It's not worth rewriting it until someone does and somehow manages to steal your customers with it.

The old system needs a big change; it's flaky and riddled with security flaws because the old language encourages undefined behavior. C was a big improvement on assembly, but it's also the leading reason everything we rely on fails frequently.

I agree! But the cost of such a move across the industry would be incredibly high, probably taking decades of highly expensive investment. Is it really worth the cost for all projects?
