In the more immediate future, we're likely to see similar tools (I'm guessing not ChatGPT itself? due to their strong stance on AI safety) gain API access to a variety of products, such that they'll be able to eg post tweets, blog posts etc, or leave reviews on e-commerce sites. There probably will be a mix of user-assisted as well as fully automated use cases.

Not quite a movable limb, but definitely we should see more in the direction of the AIs affecting the real world other than just text/image output on the user's screen.
