AI writes most of everyone's code; only the enthusiasm differs
AI-written code and belief in AI, by years of experience
The median share of shipped code written by AI is 70% under four years, 80% at four to six, 70% at seven to nine, and 65% at ten or more. Agreement that AI makes them more productive slides from 82% to 68% across the same buckets. Both spreads sit inside their margins of error, so read this as no clear relationship rather than as a trend.

The share is self-reported with no shared definition of what counts as AI-written, so compare the buckets against each other rather than treating the level as exact.
Groups differ in more than the split shown, so read these as descriptions, not causes.
