Seriously, it feels like there’s some collusion going on behind the scenes. This is the most obvious use case for the technology, but none of the big vendors have explored it.
I think it's because it turns out that taming a generative language model is really difficult. It's what we need to support more than some hardcoded simple questions, but companies like Google who are known for search want to keep their image of "use us to find what you're looking for". In the current state, their models (especially Bard in my experience) simply return bullshit and want to sound confident. They need to get beyond that stage.
But I feel you. My Google Assistant doesn't even seem to look for answers to questions anymore. All I get, even for simple queries, is a "sorry, I don't understand".
