Today I learned - from a very short "we're sponsoring Python" sponsor blurb by Meta during the opening PyCon US welcome talks - that Python is now "the most-used language at Meta" - if you consider all of the different functional areas spread across the company.
They also have "over 3,000 Python developers working in the language every day".

The live captions for the event are once again provided by the excellent White Coat Captioning - real human beings! This got a cheer when it was pointed out by the conference chair a few moments earlier.
