Off to one side is over-diagnosis. It's good to have ubiquitous sensing, and it will be really good for the detection of issues, but alongside that will be an increase in associated medical "costs" (I don't mean US $ alone: providing health services in an NHS model incurs costs) dealing with false positives.

It's a balancing act. I've now had one, and my partner has had one instance of going to see a specialist who says "you shouldn't have been sent here, this is the effect of improved imaging and diagnostics without updating the criteria for triage" -The imaging and related diagnostic tools now "find" artifacts which are sub-clinical for risk, but the triage requirements on the technician require them to report on, since "it might not be"
