This is actually a pretty good comment. The scissor analogy, while a bit on-the-nose, is very accurate. Maybe a better example would be: why is our body fooled by artificial hearts? Simply because it was built in such a way that it simulates a real heart pretty well.

Similarly, these models are built in such a way that they simulate real-life conversations pretty well. There's nothing really more to it. In my view, this phenomenon has nothing to do with intelligence or how smart we are, or whatever.
