Small hypothesis: I bet people like AI chat interfaces in some part because they are “clean” – simple text, easy to process, consistent visuals, no ads, no pop-ups, etc.
To use a cliche example: Even if it wasn’t in any way “smarter,” it’d still be nicer to ask ChatGPT for a recipe than go to a webpage to read that recipe. Its interface is a natural “reader mode.”
But… that’s not going to last.
