> Go, which is much older than Swift, Rust, D, etc.

Go is definitely newer than D, which came out in December 2001, though D2, which is significantly different, came out in June 2007, while Go came out in November 2009. And, in the grand scheme of things, Go isn't too much older than Rust, which came out in January 2012.

Additionally, from the point of view of "no UI libs," basically every natively compiled language is at a significant disadvantage on Android, even the originally intended native language, C++ (1983).
