I understand your desire for hard data, and I&#x27;ll admit I doubt it&#x27;s there. However it&#x27;s not that much of a stretch to follow from &quot;babies survive better when people are watching them&quot; to &quot;it&#x27;s easier to watch a baby when there are multiple people taking care of it&quot; to &quot;it doesn&#x27;t have to be people, necessarily&quot; to &quot;what if sensors could do it&quot; to &quot;babies live longer because sensors are watching them when humans might not be&quot;.<p>Completely pulling numbers out of my ass for sake of argument, for every 1000 babies that survive just fine without baby monitors, there might be one or two that didn&#x27;t, because mom and dad stepped away and didn&#x27;t notice the kid stop breathing. Really, people survived just fine without seat belts. We kept enough of the population to survive and even thrive as a species even in incredibly dangerous cars. But now that we have them and we recognize their value, would we go back?
