One of my colleagues predicted, when ChatGPT was first released, that AI would reduce the value of knowledge work relative to manual labour, but I disagreed as I think the main thing holding back robots from replacing many manual labour jobs at the moment is the difficulty communicating with them. I argued that ChatGPT indicated that we were not too far away from being able to tell a robot to pick the apples from a particular row and put them in the green barn as the usual red barn was being painted today. This video suggests that I was right, and I in fact suspect that such manual labour is a more realistic type of work for AI (with robots) to substantially replace first than most knowledge work, where I think it will remain as an assistant for some time.
