A Heart Attack Early Warning System, Ctd

Ezra Klein responds to the new technology that may be able to predict heart attacks:

Consider how dramatically these devices will change medicine. Right now, the medical industry is fundamentally reactive. Something goes wrong, and we go to them to fix it. This will make medicine fundamentally proactive. They will see something going wrong, and they will intervene to stop it. It’s like “Minority Report” for health care.

This is why I don’t put much stock in projections of health-care spending that run 30 or 50 or 75 years into the future. Will biometric devices in constant communication with the cloud make medicine more or less expensive? Will driverless cars prolong life in a way that saves money or costs it? Will the advances in preventive technology make medicine so effective that we’re glad to devote 40 percent of gross domestic product to it? Who knows?
