Robotics - is nowhere near the promise as well - we are nowhere near biological entities(not made from metal) with syntetic brains, not to mention biological robotic arms that humans can use as prostetics while they are regrowing natural limbs. So much to learn.
As for the Jesus. That is not really a deep subject. We know what Jesus was as a human - his real life and his violent and human nature(as a military representative of cult, that was lead by John the Baptist) has nothing to do with how it is portrayed by religion.
