The conversation between Jon and Martin where Martin starts just asking Spooky Google, otherwise known as Jon, things is really good at being exposition without feeling forced. It’s things that he might actually wonder, or that he might wonder (is there a god? would we have succumbed to climate change?) and it sets up the boundaries of Jon’s omniscience (he can’t know the future, he can’t know whether other forms of the supernatural exist, he can’t know much about the Fears, etc.) really well!
