> In short, knowing all of this info about yourself is not helpful. When it lacks greater context and, unless you know how to interpret it, is just a source of confusion and anxiety. At best, it's novel trivia.

Isn't that the service that exist.io is hoping to provide? It seems to me like their mission is providing people with greater context than just a bunch of data points. They provide the expertise in interpreting this kind of data so that people don't need to analyze it themselves.

Now, I'm not convinced that they'll be able to provide actionable ways for people to improve their lives, but I certainly hope they can! We generate a lot of data w/out much effort; if we can also use it to improve our lives w/out much effort that's a big win from my perspective.

Isn't that part of the entrepreneurial spirit: having the courage to build something even though you don't yet have all the answers?
