Language is finicky; it is constantly evolving and changing. So it’s no surprise that generational differences arise through its use. Recently the term ‘you’re welcome’ has fallen to the wayside for Gen Z, and their argument is reasonable.
In an article by Logan Mahan at InsideHook, multiple experts discuss the ways and reasoning behind Gen Z’s preferred use of ‘no problem’ or ‘no worries’. ‘You’re welcome’ has been deemed too formal, and resides for use with superiors, people you don’t particularly like, or for sarcastic purposes. When speaking with friends, it’s preferred to use ‘no problem’ after performing a favour for them. It creates an easy feeling for all those involved and takes the pressure of returning the favour away.
But the actual reason for this change: Gen Z wants you to know that they don’t mind helping you and that the favour they provided for you was, indeed, not a problem and that you should not worry about it. They were glad to help… in most cases.
