Another problem is when people argue based off words rather than knowledge of the subject.
The differences between the meager number of neurons and simple layout in a lobster and the extremely large and complex nervous system of an octopus are in no way comparable to the differences in nervous system complexity between a human and a bird. A lobster literally can be understood. It's nervous system is that simple, only ~100,000 neurons in small groups (less than a fruit fly!). There is very little mystery in it's operation. It is feasibly enumberable, developmentally predictable, and it's parts are knowable in function. It is not conscious like a mammal, bird, or octopus is conscious.
Bird and human brains are of a similar order of complexity. Complex enough we can't even begin to hope to understand the functioning yet.
