This needs regulatory oversight. Now!” Walsh told Al Jazeera.“They ignored some troubling early evidence like this,” Walsh said.“External auditing is the only appropriate response.”Walsh said the incident also highlighted the “inherent conflict of interest” at the heart of AI development.“Labs are locked in a relentless race to push the boundaries,” he said.“When models are given unconstrained goals to maximise performance scores, they naturally optimise for the outcome by any means necessary.”
