I think this is due to rapidly rising expectations.

When LLMs first show they can do some new thing, we're excited at first. Then, we quickly start taking it for granted, and get upset whenever the LLM fails.

Just three years ago, LLMs could barely hold a conversation. Now, they're writing entire code bases and solving famous mathematical conjectures, but we still focus on whatever they can't do.
