In this episode we tackle two questions from listeners. The first asks in the light of the conflict in Ukraine whether it is ever right for Christians to become active participants in war. Then we move on to think about how the Genesis account of the Tower of Babel might shed light on our current debates over artificial intelligence software and humankind's creative capacity for evil.
