This is precisely one of the reasons I prefer attention schema theory as an explanation of consciousness. It actually has a progressive build up, with each individual stage conferring an advantage while also leading to the next stage. Evolution does not like big-bang progression. And it's also very hard to explain big-bang progression in multiple, drastically-unrelated species -- such as humans and octopuses. Attention schema instead builds gradually. It starts with selective signal processing, advancing to body schema, then to attention schema, then to social schema (modeling other's bodies and attention). https://en.wikipedia.org/wiki/Attention_schema_theory https://en.wikipedia.org/wiki/Attention_schema_theory https://www.theatlantic.com/science/archive/2016/06/how-consciousness-evolved/485558/ https://www.theatlantic.com/science/archive/2016/06/how-cons...
