Help me understand the meaning

"Something being "yet to come" is more of a literary concept, or at least one farther away in time."

I found this sentence in a forum. I don't understand the meaning of this part " something being". could you easier this part so that I can understand.

the full context is below:

"I tend to disagree, but only because of the context of your example. Assuming someone was making an announcement on stage during the interval of a show, they would probably say a. rather than b.

Something being "yet to come" is more of a literary concept, or at least one farther away in time.

However, yet does get used in everyday speech, e.g. I have yet to meet anyone who talks as much rubbish as you / He has yet to demonstrate that he's serious about this / The minister has yet to make an announcement"
