Evolution built man that has intelligence based on components that do not have intelligence themselves, it is an emergent property of the system. It is therefore scientific to think we could build machines on similar principles that exhibit intelligence as an emergent property of the system. No woo woo needed.
There are lots of other analogies but the moon ladder is simple enough to be understood even by children when explaining how nothing can emerge from inert building blocks like transistors that is not reducible to their constituent parts.
As I said previously, your time will be much better spent convincing people who are looking for another religion b/c they will be much more susceptible to your beliefs in emergent properties of transistors & data centers of sufficient scale & magnitude.
So with "Real AI" you actually mean artificial superintelligence.
This is not always true, for an extreme example see Indistinguishability obfuscation.
