I mean, really? Insurance industries could probably optimize their underwriting by a few more percent than they do, but I can't see big data being all that transformative. Same in health care. A cure for Alzheimer's disease or better drugs for schizophrenia, or affordable GLP-1 drugs for everyone could change the picture -- big data won't. It won't solve the problem of getting all the crazy folks on the street to get a depot injection once a month, for instance.
