As one of the main contributors to SciNim, let me tell you that we're painfully aware of the size of our community.
But when evaluating these things keep the following in mind:
- we're very active on matrix / discord [0][1] and more than willing to provide significant help to anyone who wishes to use Nim for scientific computing
- all of us that do use Nim for scientific computing wouldn't do it, if it wasn't feasible. While we're small, we do have all functionality that any of us need & in the cases where specific things are lacking, we have the ability to call Python [2], Julia [3] and R code [4].
And just keep in mind, every community starts small. :)
