A Saber Interactive CEO denies what a former lead writer claims happened to her during development of a rideshare simulation game. The entire argument turns on a word nobody has bothered to define.
Stella Sacco, who led the writing for Rideshare Stimulator, posted on Bluesky that she was "replaced" with ChatGPT midway through the project. Matthew Karch, Saber's CEO, countered that "neither Saber nor Unigine have replaced any writers with AI". Both statements can be true because "replacement" is doing work neither side has examined.
The unstated assumption beneath this dispute is that labor substitution happens as a discrete event. A writer is hired, then fired, the transition clean and instantaneous. But game development, especially mid-project, doesn't work that way. Labor substitution in the creative industries moves in gradations.
A writer's draft receives an AI-assisted revision pass — and the revisions expand in scope. The writer's role compresses from authorship to review to approval to removal. Each step is defensible separately. The endpoint is identical to dismissal. The path there crosses no single moment a contracts lawyer would flag as "replacement." Saber and Unigine's silence on contract language, on whether Sacco was an employee or a contractor, on what "writing services" meant in her agreement. This tells you where the real liability lives.
The substitution of one labor type for another can look invisible when you obscure the category.
If Sacco was a contractor hired to deliver narrative deliverables rather than to perform the labor of writing, then AI-assisted workflow optimization is not legally or contractually a replacement at all. It's a change in production methodology. If she was an employee, it almost certainly is. The Verge didn't ask. This matters beyond this one studio because it reveals the grammar game companies will use to shield what they're doing.
