It does seem to give better answers.
But I don't think that's necessarily indicative of which kind of technology is capable of giving better search results. Google isn't what it was 20 years ago, so I don't think that what Google is now is terribly indicative of what their core technology is capable of being. They've largely allowed their search service to sink into a quagmire of content farms. They occasionally make a vague swipe at dealing with the absolute worst of it, but for the longest time they've had little incentive to put too much effort into it because these same content farms produce a sizable chunk of their ad revenue.
And they won't go down without a fight. I can't imagine it will be that easy for their crown to be wrested away by a chatbot with stratospheric operating costs that's been jerry-rigged into an ersatz search engine that nobody can afford to "reindex" more often than once every couple years. I wouldn't be surprised if a few rounds of proximal policy optimization costs more than it would cost Google to apply some proper attention to their search result quality.
