Sorry, but I don't see a lot of real substance here. It seems like "Forcing the religious idea of an universal consciousness again down to our throats".

Are spiders smart? yes. With capital letter. Some at least can be top of the game for a small arthropod. But If spiders think with their webs then we should consider the hair in our arms, our shoes and our googles part or our brain also. As philosopical idea It could have some merit, but it has not any sense in biology when what we call brain is clearly defined and delimited.
