By that logic, we should have never broken the sound barrier because we're under the same physics constraints as other biological organisms. The key difference

By that logic, we should have never broken the sound barrier because we're under the same physics constraints as other biological organisms. The key difference is that this new intelligence is not constrained by having to slowly pump ions across cell membranes in order to internally generate power for computation. Silicon transistors are much more efficient at computation than the human brain just as a jet engine is superior to to a peregrine falcon. ChatGPT could absolutely generate thousands of words per second on existing hardware.
