Big tech companies do use many languages. Sometimes smaller one as well. I deal directly with at least 5 at the moment. C++ is in this set but no Rust so far as I do not have business case for it. But do some reading to be aware.

What other recent language is used by all large tech companies.

What on earth constitutes "recent" language and where did you se me mentioning "resent"? Anyways, does C++17 qualify? What about PHP8, ECMAScript of latter editions, newer versions of C#, Java etc. etc. ?

If I understand your thinking correct let me help you with your question: what native high performance language with no GC, memory / lifetime management and with the stable release after 2015 is used by all large tech companies. Nice try.

Also what FAANGs do with their choice of tech is their own worries. They have needs that will never be encountered by majority of the rest of the world's programming.

No, language versions are not languages.

I meant in general, which languages that were created in the last 20 years are used by all big tech companies.

I was arguing that Rust is popular since it has quite a bit of adoption, as demonstrated for example by it's usage by big tech. Also, no, there is a dire need for good systems languages.
