I am an also an experience developer on the Python side and find it to be the same. Its hard to quantify the amount of time but the autocomplete does a really great job most of the time.
What is it auto completing? Most of the common things I share between projects are in the form of libraries, there is really no need for ai auto complete. Don’t get me wrong, ai is incredibly useful, but more for understanding things than autocomplete.
It's auto completing everything. Not just words or lines, but multiple lines. And it is way faster to read and see if it's correct than to type it all yourself.
