I'm a T1D and tbh it's not that hard to manage, I just wouldn't need that. But for kids or the elderly, I see a use case.
The hardest to learn was that an unhealthy lifestyle resulted in a diabetes that was harder to manage. Too much carbs, not enough exercise, etc. After adjusting my lifestyle, it became quite easy.
The most pain, in my experience, comes from the discrepancy between the CGM - measured value and the prick-test value, even when accounting for time lag. I've used several CGMs and they've all been wildly off sometimes. I have a few T1D acquaintances who relied on their CGM alone and have significantly improved their HbA1c after accounting for that.
Maybe that information is useful to you.
I don't know, Dexcom G7 is accurate enough. I do random tests from finger and it's about there a bit off but close. The previous versions were wildly off if you're having a hyperglycemia, and also G7 doesn't peak as high as measured from a finger. But in that level you already have ketones in your blood, and insulin resistance, and a bit extra insulin from the pump will not drop you to hypo.

These are exactly the kinds of people who should NOT base their diabetes management on the "suggestions" of LLMs! There is the real risk that such users lack the competence or judgement to critically assess the convincing-sounding output of an LLM.
Look into Eversense 355 (implantable), it has so much better accuracy for my wife than the Libre and Dexcom CGMs she has tried.
