In addition to providing advice to people, it can aggregate the advice it has provided, translate it into economic terms, and hand it off to some independent economy-modeling service which is (from GoogleLifeMap's perspective) a black box. Economic predictions about the costs and benefits of various careers are compiled, and eventually become GoogleLifeMap's new dataset. Possibly it has more than one dataset, and presents career recommendations from each of them in parallel: "According to dataset A, you should spend nine hours a week all through high school sculpting with clay, but never show the results to anyone outside your immediate family, and study toward becoming a doctor of dental surgery; according to dataset B, you should work in foodservice for five years and two months, take out a thirty million dollar life insurance policy, and then move to a bunker in southern Arizona."
