I think the score for Colossus: The Forbin Project is too low. There is nothing in the film that contradicts the notion of Colossus being a very, very large LLM. Although I think the film is even better than the book by D. F. Jones, only the latter mentions how, despite being created specifically for US national defense, Colossus is also fed unrelated data including Shakespeare's sonnets, because its creators do not know if it could be important.

>The two machines begin with arithmetic and soon communicate through mathematics their engineers can’t follow. That’s the most relevant prediction here: machine intellectual activity racing ahead of the people supervising it.

This misses the specificity of the scene's prediction. Colossus and Guardian are basically speaking in the style of the super-dense, almost incomprehensible-to-human chain of thought that LLMs indulge in nowadays. One might also point to the just-released news of LLMs easily seeing patterns, incomprehensible to humans, in model weights.
