My kid's circles of friends consider email to be like snail mail/phone calls- nothing but spam.
I warned them about g-products for years while they were growing up, but I needn't have worried- they see g/fb/insta/snap et al for the garbage it is.
Most of them use telegram or whatsap for communication.
Kids im speaking of are 15/17 (both girls). My youngest(boy) at 12 is more worried about football.
They use plex or whatever for sharing. They schooled me hard.
