The deadly menace of a lack of a menace

Near-Earth object surveys have found (we think) 98% of the largest objects that present the most risk, reducing the actuarial risk due to asteroid impacts from 250 fatalities per year to 64 per year. Based on past discovery rates and projecting forward through proposed future projects, over the next 16 years, we should achieve 90% completion of discovery of asteroids larger than 140 meters in diameter. The effect of this 16 years of work -- at a cost of roughly a billion dollars -- will be to reduce the actuarial risk to 33 fatalities per year. If you see asteroid surveys as a form of insurance, then you're spending about two million dollars per fatality avoided. From the point of view of insurance, this is a relatively expensive effort. Harris' point: "The hazard stuff might sell the program," but in fact, the benefit is questionable; the real value of survey programs is in the science they produce. "The scientific value of deep surveys is such a treasure trove that it's worth it right there."
"Scientific value". There's a vote winner.
