it feels like we're more comfortable to trust a device to tell us we're fine than we trust our own body and mind.

Oh and for sure, there is definitely a push toward being controlled in this way - but then for the last 50 years, there has been a push to not pay attention to reality and instead, listen to how we feel. Feelings are generally not a very good indicator of reality, as they can be based on fantasy that feels very real :)
