It’s much worse. A webpage that is presented as the result of a user input has a certain context, an embedded assumption/understanding that an inappropriate result could be the result of a malformed query. Put another way: Google is saying “here is what I found on the web.” ChatGPT is saying “this is the answer to your question” and refuses to cite any but the vaguest of sources, like a solar calculator, not even a particular one.
The danger is in the framing.
