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".

Conference presentation at PyCon US 2025 showing speaker on stage in blue shirt with large screens displaying his image and slide text: "have over 3,000 Python developers working in the language every day, which is -- I mean, there's probably more people here. Looking at you all. They're in different functional areas spread across the country. But if you look at folks making changes, Python is the most-used language at Meta. Our motivation to continue investing in Python is to support development at scale. We look forward to building solutions"

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.
