Yes, there very much is a huge barrier. The copy and the original both keep the same subject matter: intelligence/human-like behavior.
The toaster doesn't. We could do edits, and the story (original or copy) would lose all its potency.
The surprise is "but how is the richness of intelligent behavior produced from something as basic as meat/weights". Why is kind of surprising reductionism is both cases.
Whereas nobody is surprised that "a metal strip with electricity flowing through it from a power source" heats pieces of bread to a specific temperature. Even if a toaster was "metal strips" all the way down, it's nowhere near as impressive jump from substrate to behavior, nor is the behavior as important to us and touches the core of our existance.
