We’ve been enhancing our abilities beyond our natural capacities through tool use since we first picked up rocks and merging our tools has always been the logical next step. This isn't going too far. It’s simply evolution.
I think the next step is linking more directly with the brain. Even with using tools now, whether we’re moving things or whether we’re taking signals in through our ears and so on; it is the old way of doing it. There is an interface and if we can short circuit the interface to put signals directly into the brain or take signals from the brain, it’s the next step. It's an evolutionary step how humans are now technologically speeding up evolution.
