A new pancreas?
Perhaps an insulin that didn’t require you to carb count. You inject it before you eat and it somehow is able to generate the proper amount of insulin for what you’re ingesting. Your body can figure out how much it needs without you giving prior notice, I think we should be able to do the same.
It would make life so so much easier. It’s hard when you think you’re going to eat something and then you turn out not to be so hungry. Or you take your insulin and then the restaurant’s kitchen has a backup and you can’t eat right away. Or you can’t decide what you want to eat. Or you just want to munch.
It’d be convenient in about a million different circumstances.
