I can't be the only one who looks at this and doesn't think its that silly that it does that. I mean it's trying to incorporate a fact its being provided. Its insane it can do that at all. You could tune it to prefer pre-existing knowledge and not let the user correct it so easily, and to be more skeptical, but that would have downsides too. I don't think it's some big coup that you can tell it Google is a mushroom and it synthesizes that.
