Two statements, two units of measurement

Stella Sacco, who says she was lead writer on Saber's Rideshare Stimulator, posted on Bluesky that the studio replaced her with ChatGPT midway through development and that the passenger voices were AI as well. Saber chief executive Matthew Karch told The Verge that neither Saber nor the developer Unigine has replaced any writer with AI, and that the game will include an experimental free-ride mode which uses AI because the number of passengers there is unlimited.[1]

The two statements answer different questions. Karch's evidence is a company total: more than 3,000 employees, none of whom he says has to worry about being replaced by AI, plus a habit of using such tools that he dates to the studio's founding in 2001. Sacco's evidence is one product and one assignment. A studio can keep hiring across 3,000 roles and still withdraw a particular commission from a particular writer; the aggregate does not close that item. The competing reading deserves weight too: creative direction on a simulation game can change for reasons unrelated to cost, and a lead writer's contract can end when the scope she was hired for ends.[1]

Sacco's reply to the statement makes the point in the studio's own terms. If rides she wrote are in the game and rides the model wrote are in it too, then AI was used and the writing work she held shrank, whatever the total payroll did. Sacco says the studio told her about that decision in December 2023.[1]

The one place the answer could be written down

In another workplace the same week, which part of the work was done by what is itemised line by line. GitHub's usage report for Copilot now separates token spend by model, showing input, output, cache read and cache write tokens next to the credits each model consumed. That measurement was built for the buyer's budget: the stated reason is that a charge is hard to explain without seeing which tokens produced it. In the Saber dispute no comparable number exists on either side, and the game's Steam listing carries no generative-AI disclosure.[1], [2]

That asymmetry decides who carries the burden of proof. The commissioning documents, the build history and the scope changes sit with the studio; the writer holds the memory of a conversation and a store page that says nothing. Two steps would change the arithmetic without anyone having to be believed: an AI disclosure on the Steam listing naming which content is generated, and an account from Saber of how much writing it commissioned for the game before and after December 2023. Both are within the studio's gift, and neither has been offered so far.[1]
