Scientists hail ‘smart’ insulin that responds to changing blood sugar levels in real time

The article specifies type 1 a lot, Why wouldn't it also help with type 2?
Just guessing
So it might help with Type 2. But easing the live of people with Type 1 is just the bigger goal.
Because type two doesn't have issues with insulin production, but insulin sensitivity. So the pancreas produces, but the body isn't responding as it should.
And because of that insensitivity the pancreas tries to produce more and more insulin which leads in later stages to the beta cells "wearing out". At this time you'll need insulin. So a smart insulin would be a solution for Type 2, wouldn't it?
