Perhaps this should be stated the other way around – what we are made of, determines who we are. Jellyfish are made one way, and we are made another way. One is not better than the other – just different.
Since human beings operate by neuronal networks – who they are, depends on how these operate, and how fast they operate – in milliseconds. Computers are made of Silicon, and they operate in microseconds. One way is not better than the other – just different.
In Philosophy – Ontology (what we are made of) determines how we should behave (Ethics). If we do not care what we are – we do not care how we behave.
