General AI

What is the point of having a General AI instead of highly-tuned(optimized) specialized software fit for the task?
I.e. the "human-like AI" vs domain-specific software

not necessarily, but that's how scientific progress often works: emulate nature and refine it to your needs. first experimental flying machines (which generally didn't fly so good) emulated either wing flapping or lighter than air properties. it took time, research and experimentation to get from Da Vinci's drawings to airplanes.
