Pumps aren't implants, you replace them regularly. They are a massive improvement in care for many people, but they do not remove the daily toil of managing diabetes. Personally, I found a CGM to be even more helpful than a pump.

Closed loop artificial pancreases are the future, but they will still require a large amount of attention and management by the patient.

Indeed. I am not diabetic, but a close friend is, and I have observed all of the effort and uncertainty that goes into it.

My friend got a new high-end closed loop system, and it's so much better than the previous pump. There's still a long way to go before it's truly an artificial pancreas, but my friend already has much higher quality of life, and the tech is still improving.

Insulins that themselves react to blood sugar levels are another interesting path. Not that they could ever do the entire job, but they could lend some first-order stability.
