I am a Free Software enthusiast, coding mostly in Java, Kotlin and C++, but also in lots of other languages.
My mind can adapt to excell in everything techincal. Everything, you ask? Eeeeeverything! It is just a matter of how ego-vulnerable one is willing to be. I go all the way.
Therefore, I don't care much about the specific technologies or fields I work in, but rather about the social and economic impact; about how meaningful my time would be spent.
