In reply to @aintea "Do you people think": Business tech choices are more
about building a great team than about the tech choices themselves
Whatever you choose, it has to avoid being restrictive in the type and amount of
people you can hire for the job
Niche tech _(which might also include rust and even vanilla C, depending on
context)_ requires more money to hire, more money to maintain those hires and a
longer hiring process
Compare that to JS/TS, where you lift a rock and 10000 hungry-for-work devs will
throw themselves at you
A successful business its all about compromises, and finding the right team to
execute the job

So, to answer the question about Nim, I don't think the tech stack matters
It matters what the people that can build what you want to build can already
use, or is easy for them to pick up
Nim is easy to pick up for almost any dev, and stable for anything you want to
build
But you are also building almost from scratch if your tool solution happens to
be niche enough, or touches topics that the Nim community does not have
libraries for

In short:
It depends on so many factors, that I don't think this question is the right
question to ask, tbh
