This in incorrect, I have been at Google more then 5 years and the work has been in go. Most of the teams around me use go as well. But this is not to say that there is lesser java/cpp use.
You precisely made a point, it's easier and natural to say "⅏⁝⏏⌸" rather then "The pain you feel when you stumble around in the dark in drowsy stupor and step onto a plastic construction toy brick with your bare foot." It is the nuances and connotations in a particular language the bring out the 'true' meaning.
In one of the languages I speak, "hucci" means stupid, but in fun, loving way. Stupid just doesn't cut it.
