That is very much the case at the current iteration of AI, but that should change with the introduction of world-mapping, computer vision, and world interacting AI. If machines are built out so that they are constructing accurate world-maps of how the physical world works and how to operate in it, then AI will begin to be able to out-invent human tool concepts and push past the horizon of what humans have so far been able to dream
Why? They're still only going to be trained on human input or input generated by them as derivatives of human input.
Modality change might expand their usefulness, but I don't think it changes the basic parameters of their operation.
Learning to swim might let you see a coral reef, but it won't turn you into one.
