@phire I think the most reliable number I can find is from Stack Overflow’s 2024 survey, in which about 62% of respondents indicated they were using AI coding tools. https://survey.stackoverflow.co/2024/ai
(SO has further details on their survey demographics which I would personally assume bias this number in the upward direction, although I don’t know for sure.)
@davepeck @phire Good on you for researching it! To OP's point though, 62% is pretty far from "almost every".
