> it sounds like the real news is just how difficult this problem is - even for Apple
I've worked in this space for 5 years now, and this is not news to any of us. Today, a tiny, noninvasive device, that is accurate enough to make insulin dosing decisions, is pure science fiction. It's probably not impossible, but we'll literally be able to use stem cells to regrow human pancreases and straight-up cure people of diabetes before this tech becomes a reality. (We're much further along that path.)
What is interesting about this though is the possibility of using this device for non-diabetics who don't need extremely accurate glucose readings. A rough approximation of someone's blood glucose levels is enough to learn how your body reacts to different types of foods and exercise, and would be helpful for amateur athletes who can't afford to purchase real continuous glucose monitors, as well as pre-diabetics for whom CGMs aren't covered by insurance.
