It turns out that something has been watching the Earth in minute detail since before the solar system was formed, down to a sub molecular level. It can give you the answers to any historical questions, but not things like what someone was thinking or feeling.
All the world’s problems have been solved, and the information is only used with the strictest privacy, e.g. you can only get information on living people with their permission, or if you’re a member of law enforcement solving a crime.
The question is, if you have a hobby, job, or other reason to research the past, like being a geologist or genealogist, would you take the answers, or would you prefer to do the research yourself?
Definitely would want the easy answers. And even the definition of murder is divisive amongst people (is it ok in self defense? Is it ok if they make mocking cartoons of your god?), so do you need like 98% of people to agree it’s a crime?
