Why did people stop saying you're welcome?

Have you ever noticed that people seem to be saying "you're welcome" less and less these days? It's almost like it's become a dying phrase. So, why do you think this is happening? Is it because people are just becoming more reserved or is it something else entirely? Is there a cultural shift taking place that's causing this change? Or could it be that people are just finding other ways to express gratitude and appreciation? Whatever the reason, it's definitely something worth exploring and discussing further.
