Common misconception. I always explain it to people that insulin pumps are sort of like a manual, external pancreas. You have to tell them what to do. They have no way to know what's going on in your body; they just deliver insulin as they are told to do so. To use a pump effectively, you need to know how your body reacts to all sorts of conditions and situations and program it accordingly. The advantage of the pump (over multiple daily injections) is that you can have a more flexible life and can really fine tune things for the way your body works, but it takes attention and effort. This is especially true during pregnancy. (Thanks, hormones.)
Closed loop systems (where you have both a pump and a sensor to know how the body is reacting, so the system can "think" for itself) are very much the holy grail of the technological approach. (Other people are still hoping/going for a cure, but personally, I think a closed loop system is a way more achievable goal, and one that I will more likely see in my lifetime.) There are a bunch of closed loop systems currently in early trials. Just hazarding a guess, I'd say they are probably a decade away from a marketable system.
I doubt they will add delayed boluses; they are not a common need and it would tough to get that type of feature past most national safety agencies (the FDA and the like.)
STILL babysitting sugars. Very annoyed with myself about this.
Oh, and pumps are relatively new, but not that new. They've been around since the late 70s, but the early versions were enormous and not very flexible. They really got going in the 90s and 00s.
