Web and app designers: no one born in 2025 is using your app/site.

Defaulting the birth year selector (looking at you, airlines) to the current year means every single person who uses your software has to scroll further, for nothing. On a phone that is a PITA. If your software/site is for 12+ then make it 2013 at least. If it's 18+ then 2007 at least. Better yet, make it 2000.
