It's not ChatGPT what we should be putting in our forecasts, but its successors. And, from what I have been reading, our AI folk are coming with better performers all the time by chaining multiple neural networks, "making modular brains", so to speak. Any argument that starts by saying "ChatGPT is very bad at X, humans will always do X," is flawed IMO. So I think that any job that can be done by a non-human is up for…
The low-hanging fruit IMO are most likely to be anything that is done entirely via/inside a computer. Because interacting in the digital world is much less of an issue than having to deal with digital + physical world like manual jobs do.
That's not to say it will take all computer jobs but those intuitively seem like they will be the easiest for computer-based AI to do.
Something like working in a kitchen is a long way off (or at least will require a redesign of kitchens from the ground up or humanoid robotics that are effective, reliable, and reasonably cheap). Whereas if your job is already entirely done via computer with little real world engagement, then it will be much easier for AI.
