Project Hail Mary landed in theaters on March 20, and while the Ryan Gosling sci-fi flick nails the human-alien buddy dynamic, it glosses over one tricky detail. The movie has schoolteacher Ryland Grace and his extraterrestrial friend Rocky chatting about abstract concepts like friendship in record time, even faster than in Andy Weir's original novel.
There's an obvious reason for the shortcut. You can't have a compelling buddy movie if your characters spend half the runtime pointing at rocks and grunting. But for anyone who's ever struggled through Duolingo or tried explaining something without a shared language, the speed feels off.
Ars Technica did what any self-respecting tech publication would do. They called up Dr. Betty Birner, a retired linguistics professor from NIU, to break down what real communication between two completely different intelligent species would actually require. They're covering cognition, pragmatics, cooperation, and the messy reality of language acquisition when you can't even assume your conversation partner processes reality the same way you do.
This matters if you're thinking about AI communication interfaces or how we might actually talk to non-human intelligence someday. The gap between gesturing at objects and discussing abstract ideas is enormous, and we're building systems right now that have to bridge similar gaps between human intent and machine understanding.
Weir himself weighed in on the linguistic shortcuts too, acknowledging the narrative tradeoffs. Sometimes good storytelling and technical accuracy pull in different directions, and in this case, the movie chose to keep the plot moving.
The film apparently goes lighter on hard science than the book but leans into the relationship between Grace and Rocky. If you're into sci-fi that prioritizes character dynamics over technical precision, it sounds like a solid watch. Just don't expect a masterclass in xenolinguistics.
