I'm a type 1 diabetic; I use OpenAPS, an open-source DIY system that does this, and have made some code contributions to it. So what this article is talking about is, basically, taking the thing DIYers are already doing, and making a more foolproof, FDA-approval-grade version. And I'm sure they're massively better in terms of how fiddly they are to set up and get working, but the end result is actually worse; they wind up not including features like autotune (which auto-adjusts basals and carb ratio based on historical data), because there's less risk of liability if they make doctors do the tuning, even if the doctor is only looking at the patient's data once every six months and is doing a poor by-eye approximation of what the algorithm does.
