I felt similar at the beginning but then I realized the suggestions were suboptimal, and it happened like 50% of the time. Usually not completely wrong, just imitating something that was already written, but sometimes introducing subtle bugs. So in the end it actually made me less productive because I had to stop my flow and start analyzing if there is no catch in the suggestion. It was a bit tiring and in the end I decided it's easier for me to stay with the flow.

I'll give it a try next year, maybe it improves to the point where the number of suboptimal suggestions falls to 20% or so, it would be much easier then.
