It is no better than just using any of the existing chat tools. The "sources" it provides are rarely ever relevant to what is asked, and certainly isn't valid attribution.
To elaborate, I'm mostly disappointed. Attribution and ethical aiAI is all marketing/the CEO talk about and yet we never see it. There was one experiment that did something half decent at least in that it provided results directly from real content that actually exists on SO rather than just being an unattributed chat bot; it was probably the closest we'll ever get to having real attribution, and that was Overflow AI Search. It wasn't perfect, but it served a singular purpose that was unique to SO. This doesn't. It's no different than the new "SO Jobs". It's just a chatbot incorporated into a page that is SO themed. Sure... it shows some SO questions on the right... sometimes they're relevant in one way or another, but that entirely misses the point of attribution. It's just noise in the right column that might as well be hidden, most of what it surfaces is 7-13 years old anyway and it's rarely relevant to the actual query other than being about a similar language or using a method mentioned within.
