These systems are totally obtainable. It is only liability holding the movement back (since an accidental dose of insulin can kill). Even that is just slowing down the process. The largest difference in quality of life for those with diabetes, imho, is still better quality insulin. Humalog/Novolog are the fastest. For me personally, they begin work in about 30 mins and peak after an hour, with a tapering tail of 1-2 hours. By contrast, natural insulin works within a couple of minutes. For these devices, the largest tech bottleneck has been the CGM, since the technology for delivery and control logic is akin to a PID. Only 2 fronts remain to mechanically cure t1d: an accurate, second-by-second CGM; and a faster insulin analog. Only 1 front remains to have a mostly "hands off" but still clunky mechanical cure—the C.G.M. From there, it is simply a matter of comfort and convenience. The quality of life difference between managed diabetes and unmanaged diabetes is astounding. Having an A1C higher than 8 or so is almost like going through life constantly tipsy, without any of the fun. Also, as is typical with any health condition, diet and lifestyle play an enormous role. For me, heavy daily exercise and good eating has made diabetes management ridiculously easy. Lastly, "move fast and break things" emphatically does not work with insulin delivery devices. Overdoses of insulin are debilitating, can occur without the patient's knowledge, and can lead to impairment (like car/equipment accidents), unconsciousness, brain damage, or death after a short while.
