✨ The World’s Oldest Story? Astronomers Say Global Myths About ‘Seven Sisters’ Stars May Reach Back 100,000 Years — "Why are the Australian Aboriginal stories so similar to the Greek ones?

Addressing this gap also implies recognizing the implicit norms and values integrated into these systems in ways that cannot always be foreseen by the original designers. With EAI, it is not just a matter of deciding between the right emotional models and proxy variables, but what the responses collected signify in terms of human beings’ inner feelings, judgments, and future actions."
