A major follow up to GPT-4 later this year is rumored to be (far) superior at logical reasoning than GPT-4. What's likely to happen if that becomes real?
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.
There were independent efforts to create AI agents since last year as well. AutoGPT and BabyAGI iirc. They didn’t go far probably because the LLM used was not good enough for that.
