Here's the inherent problem – insulin is a lot more dangerous on it's own than with any sort of hybrid loop system. The safety having a system like openaps - which includes a LOT of fail safes - is far greater than what a type 1 diabetic can do on their own. 1 in 20 people will die in their sleep because of hypos because he or she simply isn't fortunate enough to feel the blood sugar dipping and wake up to treat. The OpenAps safety measures are far far greater than what we have as a normal person regulating their day-to-day insulin dosing. I will sleep a lot easier knowing that I have something else watching, determining whether the boluses he's given might be corrected slightly so that he doesn't go low or high. Read about it at openaps.org – look at the reference design, and read about the fail safes where the pump will revert back to preprogrammed basal rates if batteries run out. Quite frankly anything with Type 1 diabetes is terrifying. At the end of the day, the risk with type 1 is too high for us to wait any longer.
