Complete lie.

ARC Raiders uses AI for generated voice or TTS; it's hardly in the same field as generative AI which is mass scraped from the internet and churned out of a matrix math black box. They paid voice actors for the training and likeness, and the AI is used for future flexibility, and the VAs know this and its part of the contract they sign

They also use AI for the robotic kinematics which looks absolutely fantastic. When you blow up robots they zoom around and correct themselves exactly how you would imagine an evil robot to behave
