It's certainly true that it would be lovely to have new medicines. But perhaps what's really at stake are three more intangible M's: mechanisms, models, metaphors. Thank you.

There's a lot of talk in technologyland about the personalization of medicine, that we have all this data and that medical treatments of the future will be for you specifically, your genome, your current context. Does that apply to this model you've got here? Siddhartha Mukherjee: It's a very interesting question.
