- Why are we training AI to be like us? They should be complementary! - How do humans learn concepts with so much less data? - Why would you invest in education when AI seems competent? Some good questions from this interview by @DaveNadig youtu.be/1sx7CIX2j4k

My 7yo just got mad at his brother and called him ugly, and his brother got really upset about it and started crying. They’re identical twins. Identical. Twins.
