That might let it encroach more into some fields like law where it's almost good enough already. Shitty time to be a junior lawyer, firms are going to hire and promote people not for their legal skills but for their ability to manage/attract clients.

In general though, I don't think the extra reasoning ability is going to enable it to displace that much farther than it already will, GPT lives in a box and responds to prompts. When it's connected to multiple layers of real-time sensor data and self-directing, that'll be another story.
