In a realm where physics meets the essence of life, Walker and Davies explore how life’s complexity might be encoded in algorithms. They suggest its emergence is akin to a phase transition, where information gains control over matter. This shift in causal dynamics could mark the boundary between non-life and life, offering a fresh perspective on the unique information processing that characterizes living systems.
