Rewriting something, or writing something new but with past experience always produces a better product. Some people still attribute that to using a new language or framework, or market their new product that way.

But the real driver is the rewrite, not the tools. In that case, what's interesting is the algorithm, not the language it was implemented in.

Reminds me of a famous YouTuber making videos about new tech. Every video starts with "a company based in <name of a country> announced..." or "researchers from <name of a country> found..." - This is annoying. Does the country matter? Do people ignore or mock inventions from countries they don't like, writing on HN that they should be reinvented in another country because other countries suck? Fortunately not. But when it comes to programming languages, they do. And this is equally ridiculous.

This is such a core idea that as you find it really surprising how much it gets overlooked.

IMO, another important aspect of rewrite is that it's usually pretty easy to get 70% of the functionality for 40 % of the work. But as one approaches 100% feature parity , plus handling all the corner cases, the transition from prototype to production ready things equalize pretty fast.

Not to mentioned the unknown unknown that the new language might also bring.
