I want my damn Delta then! Lol
I often see people assume humans are conscious because we are more intelligent than other species, but we have already developed AI capable of processing data and making decisions that would dwarf the capabilities of a modern human. Yet, no consciousness as far as we can tell.

I would argue this is kinda faulty reasoning. Everything AI knows how to do is because a human told it how to think through coding. It's not smarter than humans it's just faster. Give a human enough time, and it can do the same calculations.

. The organisms we have found to pass the "mirror test" or even come close are all social animals.

While I agree humans being social have been key throughout our history you kinda disprove yourself by bringing up "mirror test" as the animals that recognize themselves in the mirror are generally regarded as extremely intelligent (Elephants, Pigs, Dolphins, Parrots, and Crows) 
Another thing you brought up is language. Is that not another sign of intelligence right there? Parrots are seen as amazing smart for being able to speak and then look at humans with are insane amount of different languages with their own rules and dialects. >

There is definitely a correlation between intelligence and self awareness, and they likely evolve together. I am just positing that the need to network is what creates the emergent property, not intelligence itself.
Parrots are also very social animals, as are crows, another highly intelligent bird. >

Yeah, that was my point. Every creature that you can argue that has self-awareness is extremely intelligent that's self awareness isn't beside intelligence but directly decended from it. >

I think this might have changed my view. I will adapt it as such:
Adaptations that foster networking (ie, required for social animals) increases intelligence and the ability for self awareness (ie consciousness) to emerge.

A slight difference, essentially just a change in order of how these properties come about.
