Hm... I wonder what your use case it. I do the modern Enterprise Java and the tab completion is a major time saver.

While interactive AI is all about posing, meditating on the prompt, then trying to fix the outcome, IntelliJ tab completion... shows what it will complete as you type and you Tab when you are 100% OK with the completion, which surprisingly happens 90..99% of the time for me, depending on the project.
