I wonder if there's any good reason to reduce my pessimism about it: I can't help but think there are such strong economic incentives against having a cure (vs ongoing treatment) that it's very unlikely to become available during my lifetime.
So think disruptive tech. A new player comes into the market with something that obsoletes the old tech, and maybe destroys a whole market. But that new player makes their own money off it.
So yeah, maybe Tandem, Dexcom and Medtronic don't have a big incentive. But someone else can make some real money if they can find a cure or novel treatment that obsoletes all those others things.
