Studies regarding life expectancy tend to need historic data. I don't think "todays technology" has been around long enough to have a significant impact.
I think life expectancy has been discussed on other threads you have started,

I chose to do as much as I can to minimise the impact diabetes has on life expectancy (keep my blood sugars within range as much as possible) without detracting from the life that I live. If I am comfortable with what I am doing, I do not worry about how many years I have left - my guess is I won't be taken off by anything diabetes related.
