Yes
With the code often being repetitive (but not similar enough to e.g. be extracted to a separate function) the auto-completions definitely save a lot of time

Helped: Auto-completions for repetitive code that isn't similar enough to extract
Got in the way: Lack of documentation, complexity, and context limits
… That said, tools like GH Copilot certainly gave me at least 10% boost. With the code often being repetitive (but not similar enough to e.g. be extracted to a separate function) the auto-completions definitely save a lot of time. While I'm sceptical as to how far LLMs will go, AI as a whole (probably with different architecture in the future) will definitely go far beyond any productivity improvements currently possible.
