Re: Would you prefer to be on insulin injections or on a pum
There are some very good reasons to the couple of points you mention.
A pump can provide exceptionally flexible basal insulin which can be tailored to the circadian rhythms. I found that Lantus (whilst better than ultratard of the 1980s) didn't really last for the advertised "24hr flat dose". (It also stings like anything as it needs to be acidic to make the microcrystals on injection). That said, I did use it successfully since its introduction.
Now, for "closing the loop", my electronics chums ALWAYS ask about this. We have a bit of a problem compared to a pancreas. The glucose monitoring MUST come through the fat layer under the skin. The insulin MUST diffuse through the same fat layer the other way. It takes about 20-30 minutes. ANY "closed loop" system going via the skin automatically has a 40-60 min delay in it. THIS is the reason we're not going to see any advance there. By the time you've got part way through digesting your sticky-bun your automatic pump system may be able to respond. So we have to rely on a manual "I'm gonna eat that in a bit, so I'll pre-empt the delay & deliver some insulin now" (even so, we still have to cope with 30mins insulin-delay).
There is some work being done on a below-the-skin, straight-into-the-liver which will, of course work around the fat-layer problem, but call me squeamish, but the idea of a permanent hose deep inside me doesn't sound appealing. (Mind you, neither did a pump, 20 years ago!)
If we could just work out how to stop the body from keeping killing off the peefectly good islets of Langharan all type-1s keep making, we'd have a cure (but for the last 35 years "the cure" will "only be 10 years away". So I think I'll stick with my new pump!)
