I skimmed much of it and read portions. Some of it was over my head but you wrote it very well, helping me to understand the issue you researched including the basis for your conclusions…nice job! I especially liked your airplane metaphor about using insulin without a CGM (page 40). There was another jet crash recently that was caused by a bad sensor.
I am not sure I agree with your last paragraph in the conclusions…Let’s say you got your wish and everybody uses hacked closed loop systems. That means commercial tech will not develop further (including each company’s proprietary algorithms etc.) and the tech will never be available to “the masses”. All the people out there who need the tech but are not tech savvy enough to have confidence in a hacked device will be left out. My guess is that would mean closed loop tech would not be available to a large percentage of diabetics in the US and the vast majority world wide, because they would never trust a hacked setup enough to use it.
