The basis is that this is what we know to be human consciousness is to a degree relateably similar to our own. I do see your point but IMO, a dramatically different form of 'consciousness' comes with the risk of being something completely different from what we consider 'consciousness'. One of the great challenges with speaking about 'Self-awareness' aka consciousness (sometimes incorrectly confused with sentience, sapience, phenomenal experience etc) in AI is that we largely lack the vocabulary to properly capture the mutli-dimensional phenomena that most understand simply as 'consciousness'. IMHO, an ant or dog is 'conscious' in that it can perceive the outside world and make decisions about how to respond to it or operate within it... but we know that we operate at a different level of self-awareness including metacognition. Other forms of 'consciousness' will certainly manifest in future AI systems and perhaps already have but the models and architectures of today lack a number of key features that a human like consciousness would be based upon... a short list might include a persistent, unified self-model across time; continuous learning and development, embodied perception, interaction with the world; intrinsic goals, drives, emotions and deeply integrated metacognition—awareness of its own thoughts, uncertainty, attention, and intentions.
