Its a fundamental question to us what consciousness is, who has it, what levels or qualities of it gets.
Only 50 years ago the nazis dehumanized mentally and bodily disabled people.
Other cultures to this day lock humans away with mental illness because they don't understand it.
The complexity of LLMs reached already dimensions that are not that far away from the complexity of human brains and we are only at the beginning of this journey potentially.
World models are getting developed and we havent even tried to build systems similiar to what our brains architecture with a default mode network would look like. We only throw massive amount of resources onto LLMs.
