While I also love to take part in cargo cults, you should probably fit some good blinders on before looking over at Nubank’s stack.

I wish people would stop bringing up Nubank when it comes to Clojure/FP as if it's some sort of mic drop that proves that it's the Right Way to develop financial software. When you have to keep bringing up the same example, it's not a very good argument.

There are always going to be niche langauges and mainstream languages, and as a result, users of niche languages will always have to "justify" their use of such. To investors, to potential new users, to potential colleauges.

They're not having a bash at $your_favorite_langauge. Or suggesting that nubank couldn't have been built on any other platform. They are simply responding to the oft-stated question "are there any examples of it working at scale".

What do you care whether it's "the right way" to develop any kind of software? "Clojure" was in the title. If you don't like Clojure, skip along to the next article.

Sure, I get that they have to justify themselves, but when the answer to that question is (almost) always "Because Nubank!" for the past 10 years it doesn't feel like much of a justification.
