Because you are in a chat UI now. This is a skill issue - when you change your mindset that Google is now a chat UI to a LLM and not a query engine any more, you'll get better results. If you try the same zero-context prompt with chat.com for example you get a similar "want to talk about it?" response.

Try asking it "Tell me about the "Dario will never come over" meme - give me some of the example original tweets" for example and you get a timeline, tweets etc as the AI overview. Pretty useful really.

Tl:Dr - just like people, you need to give it some context.
