Same here, I basically turned off all the auto-complete things everywhere in all the tools I am using, can't stand it. And just before reading your comment, I had a google doc I edited in the other tab and thought, how annoying are these auto suggestions actually. Not helping at all, instead a distraction (to me).

For AI coding I'm using Aider as a docker container in the terminal in the IDE and I love it. I can write what I want how I feel the prompt to be necessary and then (and only then) it makes the changes or runs whatever I requested. The IDE runs uninterrupted and without any "smart suggestions". A tool for every job. Sometimes I do a lot in aider, sometimes I don't open it at all, but its all separated where what happens when.

But yeah, anyways, while not as strongly feeling as you (probably) towards auto suggesting mid way through my sentence, I at least feel they are more distraction than help to me.
