If my company's software is built with 10 million lines of C++, and the software works, how would you convince the stakeholders that a rewrite is worthwhile?

Convincing people to switch because "it's better" is not very compelling if I have working code that is making money.

If you like another programming language, use it. I will continue using what works for my needs, especially when I already have working code.

I am not really interested in having people switch who don't want to and are perfectly happy with their language. I am proposing the r&d of a way to coordinate people switching who would like to switch languages, but only under certain conditions, such as if their would be jobs in it and sufficient expected growth in attention to the language's development.
