So non meme language and not Go?

What languages are acceptable then? You may need to provide a definition to prevent confusion.

I mean languages that have been in existence for more than a decade and aren't controlled by a single corporation.

Go has existed for 11 years. It's probably safe to say that it won't die off soon. As for the control part: What could Google do to Go that would affect you as a user of some software written in it?

Deprecate it.

If a programming language has exited for 11 years I'd be more worried about the author of the software dropping that than the author of the language deprecating the language. It's the Lindy effect.
