In all human history, efforts to hold back the tide of technological progress have never worked. Instead of adopting a Luddite fear of data and math, we should use both for all useful ends as soon as possible.
The example about cancer doctors in TFA is perfect. "more deaths = worse doctor" is a poor metric, because advanced cases have higher deaths in general, leading to a disincentive to try to help people with advanced forms of cancer. That's a terribly perverse incentive, and one that should be avoided.
Fundamentally, a lot of this stuff comes down to a lack of nuance in metrics, leading to some nasty effects down wind.
