In Lucy there was a car chase. Lucy was driving and there was a police officer in the car. Lucy was driving extremely fast when officer said:    Better be late than dead   In reply Lucy said:    We never really die   What did she mean? At the end of the movie we saw Lucy tell the officer that "I am everywhere." I'm guessing she became immortal, but normal people are mortal. What did the writer actually mean? Even Lucy didn't know at that time what's gonna happen when her brain usability reaches 100%.
