I think the only real measure is ‘consciousness’ as I will argue that a PMIC chip would qualify as ‘sentience’ when it comes to detection and logical management of real world variable systems.
If ‘sapience’ is just wisdom, and wisdom is just the timely application of knowledge, any current transformer based LLM can take in knowledge and distil a solution that could be called wisdom if it came from a human.
Consciousness is hard to test. How does a human generated dataset create a model with the ability to tell us the answers to questions we can not ourselves answer about life, the universe, and existence?
