Face it! People do things because they enjoy it. To them, it doesn't matter if it's obsolete.
Why do people enjoy doing things that are obsolete, especially inane convrsation?
It's only your opinion that something is obsolete. If they enjoy what they are doing, why do you care? In addition, the inane conversation that you refer to could actually be relevant, but because you're talking to someone you'd rather not, you've decided to label it as inane, Perhaps someone is trying to get to know you better.
Because most people are not antisocial and actually enjoy talking to others. Conversation is not obsolete.
