If the XMR code wasn't a shitload of C and written in some higher-level language such as Scala, I would enjoy coding it. Sorry I don't use C any more except for the optimized smallish portion of a code base. I wrote 10s of 1000s of lines of assembly and C code in the 1980s. Enough of that.
And thus I also like to code in high-level paradigms.
1. There is exceedingly little C except the crypto libraries (essentially copied from another existing crypto library project), which we aren't working on because existing crypto libraries are fine (other than verifying that the code has not been tampered with and tracks upstream fixes if any). The bulk of the project is C++
2. Simulations, prototypes or other contributions can be in any language. Tacotime's simulation used Python. Prototypes have also been doing in Python and then converted to C++. Other work has been done with Matlab, and probably some others I don't remember. Scala or well-presented math or anything else is welcome and useful. Vague assertions of uncertainty and doubt are close to the definition of FUD. No one is trying to suppress that even (futile in practice to even try anyway), but I am pointing out that it isn't useful to Monero any other project.
