Good to know that you thik about the future development on MorphOS. :)
However I am not going to looking for a new language. I would like to fully use what I have today on MorphOS. :) I heard that Rust is very modern language so maybe someone will be interested in programing in the language.

I use Swift at work, C/C++ at home for hobby projects and Python for a helpful tools/scripts. C/C++ is good enough on MorphOS, SDK is ok, environment is ok, Git works. I would like to have more complete Python 3.x for MorphOS because now I have to use some ugly workarounds in MOS-version of scripts. :( Unfortunately without Yomgui we probably will not see new versions of Python 3 for MorphOS.
