“Before performing the study, the #developers in question expected the #AI tools would lead to a 24% reduction in the time needed for their assigned tasks. Even after completing those tasks, the developers believed that the AI tools had made them 20% faster, on average. In reality, though, the AI-aided tasks ended up being completed 19% slower than those completed without AI tools. […] Overall, the developers in the study accepted less than 44% of the code generated by AI without modification. A majority of the developers reported needing to make changes to the code generated by their AI companion, and a total of 9% of the total task time in the ‘AI-assisted’ portion of the study was taken up by this kind of review.”
