I wouldn't call closed loop systems much of an advancement... Sure, it doses insulin automatically based off of CGM data, but it's barely any better than just injecting yourself. Cons even outweight the pros for some - being constantly attached to a device is no fun. And the slugishness of exogenous insulin (both: the way it is injected and its time of action) diminishes any attempts to achieve precision using CGM data and algorithms in controlling diabetes. Not to mention CGM data isn't that accurate/rapid enough also. All in all, it's just not efficient, calling these systems 'artificial pancreas' is more of a marketing gimmick than reality, thus why a proper cure is needed.
