The price of insulin is already rising: there aren't all that many generic manufacturers of it, leaving them in a competition-free market. If this takes off it's going to suck up a good chunk of the marketplace, and probably leave us with maybe one or two generic manufacturers - enough to have an effective monopoly. Insulin prices will spike the same way epi pens did.
Good tech. But sad re. what it's going to do to patients for a while.
