I'm guessing the answer is a combination of synaptic latency and ethics. The human brain's latency is relatively slow relative to traditional computing. The brain's synaptic latency is measured on the order of milliseconds, while a modern IC's latency might be measured on the order of nanoseconds or even picoseconds. As messed up as it is, using biology as you describe might actually be safer once we get close to AGI, even if it is creepy as hell. There's something to be said for having a machine that's physically limited to thinking as fast as a human can (even if it is vastly smarter), versus one that can figure out a new branch of physics in the time it takes to blink.
