Danny Sullivan from Google confirmed on Twitter that even with the international/global release of BERT to 70+ languages, it still impacts about 10% of queries where BERT is live in. The other 90% do not use BERT for understanding queries and content.

Here is the tweet where Danny said this:

Danny said “It varies by language but is generally in line with the 1 of 10 figure we shared about US English.”

So still, while Bing launched BERT fully, globally and for all queries. Google launched BERT now for 70+ languages and for only 10% of all queries.
