That needs a citation, and context. Globally? The USA? The Valley? Where is this number from?

"90% of professional developers were using AI coding agents at work at least weekly in one form or another (local agents or remote cloud agents), with 68% using them daily."
Re. context:
"The Developer Ecosystem and AI Pulse surveys are localized into eight languages: English, Spanish, Chinese, Japanese, Korean, German, French, and Portuguese. We apply quotas on the required number of responses by region to help achieve accurate global representation. ... The Developer Ecosystem Survey has been statistically reweighted to better represent the global developer population by region, employment status, programming language, and familiarity with JetBrains products"
(The survey was run on Jetbrains instagram page, apparently. I mean… that is a bit of selection and narrowing going on there)
Notice how half of them have heard about Jetbrains!? I don't know any developers I would be confident know about Jetbrains (even among AI-using developers)
(Also the graphs don't really support the idea that 90% are using them meaningfully for software development.)
