The author is describing the oft' maligned and perhaps misnamed Sapir-Whorf hypothesis -- or linguistic relativity if one prefers to eschew eponymous hypotheses. That is language influences (weak version of the theory) or determines (strong) how you think. A perfectly cromulent proposition. Ineluctably leads to arguments around the relative benefits of deep specialisation versus a T-shaped skill set, which in turn invites bureaucrats to make us all uncomfortable by injecting regrettable phrases like 'generalised specialist' into the vernacular.
