Former Saber Interactive lead writer Stella Sacco claims the studio swapped her out for ChatGPT on Rideshare "Stimulator" midway through development, with AI also generating passenger voices at one point. Saber CEO Matthew Karch fired back with a statement insisting no writers were replaced on this project or any other, that the main story came from real staff whose numbers have tripled since 2023, and that the company's 3,000-plus employees face no AI replacement risk. The catch: Saber openly admits the free-ride mode uses generative AI and voice tools because the passenger pool is supposedly infinite, a detail missing from the Steam listing despite Valve's disclosure rules. Sacco countered that calling the core story human-written while outsourcing the endless dialogue to LLMs is a distinction without much difference, and community threads on Reddit and Steam discussions are already lighting up with calls for proper tags and transparency. The real story here isn't one writer's firing—it's another major studio trying to thread the needle on AI use while dodging basic accountability on a platform that demands it.
