I was looking at the comparison like this:<p>we knew that many thousands of people were dying in car crashes and also that people wearing seat-belts survived crashes at a much higher rate.<p>we know that a small number of kids die but we don&#x27;t have that same level of evidence that the proposed solution actually works.<p>That&#x27;s an argument for doing more studies but not for buying a bunch of IoT stuff at steep prices.
