It's a good starting place. As an analogy imagine someone wanted to look up the definition of a word. If someone wanted to know the definition and they went out and crawled the entire internet, built an LLM, and then asked it for the definition you would wonder why they didn't check an existing dictionary first. I wouldn't consider it silly at all to always check a dictionary or existing LLM first when you want to know the definition of a word.

Wanting to know the definition of a word is not an original problem. Similarly wanting to know what's in an image is not a new problem either.
