What programming language do 20-year-olds use?

In the interest of converting vague correlations into divisive stereotypes, here are some programming languages, sorted by the age of the programmer:

• 70 year-old programmers code in FORTRAN
• 60 year-old programmers code in COBOL
• 50 year-old programmers code in C++
• 40 year-old programmers code in Java
• 30 year-old programmers code in JavaScript
• (I don't know what 20 year-olds do; something on smartphones?)
• 10 year-old programmers code in Minecraft command blocks
• newborn programmers (will) code in Code-a-pillar*

• Everyone codes in Python for their hobby projects, because life is short.

 * I am not affiliated with the makers of Code-a-pillar. I just think it's funnier to have the 20-year-olds be the only ones I'm confused about.

Corollary: Asking programmer job applicants what their strongest programming languages are should be illegal in the USA, where "age" is a protected hiring category.
