We won't live in that world in the next decade or even in the next 100 years. The technology upon which GPT is built is a dead-end in terms of human-level intelligence.

GPT is an elaborate parrot. As convincing as it is, it's not actually fully capable of doing most if not all tasks that competent humans can do. The largest takeaway for me is that it has shown that intelligence can be mimicked pretty well and perhaps many people are more like parrots than they are "intelligent" creatures.
