Explaining Data Science To Your Grandma

I cannot put exact words on my frustration. I have been a Data Scientist for 3 years and I have been struggling for most of these 3 years to explain to my family what the purpose and day to day activities of my jobs are. First of all, my family only speaks French and Data Scientist does not translate fully to French. Officially, the French government proposed a translation: "expert en métadonnées". Spoiler Alert, it means nothing to anyone.
