David não estava aprendendo a falar a língua do Engineer, ele estava aprendendo línguas antigas para poder decodificar a linguagem do Engineer. Isto é baseado na teoria de que as línguas humanas são derivadas da linguagem do engenheiro.
In the scene David is learning the building blocks of language and we see him taking a lesson in Proto-Indo-European (PIE) Linguistics, where a holographic professor, takes him through the ABC’s and recites Schleicher’s Fable. An artificial text composed in the reconstructed PIE, in 1868, to demonstrate the language’s use.
