Maybe you’re right about modern LLMs. But you seem to be making an unstated assumption: “there is something special about humans that allow them to create new things and computers don’t have this thing.” Maybe you can’t teach current LLM backed systems new tricks. But do we have reason to believe that no AI system can synthesize novel technologies. What reason do you have to believe humans are special in this regard?
In the grand scale of things, a computer is not much more than a fancy brick. Certainly it is much closer to a brick than to a human. So the question is more 'why should this particularly fancy brick have abilities that so far we have only encountered in humans?'
If we're going to be reductionist we can just call humans "meat sacks" and flip the question around entirely.
