techniques involving immunosuppression are not breakthroughs. Immunosuppression alone is enough to reverse type 1 diabetes, it's an auto-immune disease.

But obliterating the immune system has more risks consequences than insulin treatment, so it's never done in practice..

I read an article months ago that they had already achieved this in China.

As a diabetic myself, I say "OK good", but living in this dystopian hellscape, do I think I will live long enough to benefit from this? Probably not.
