A Microbial Future

Microbes have existed on Earth for almost 4 billion years; 3x as long as multicellular organisms and 1000x longer than humans. So what does the future hold? Will recent advances in genetic engineering enable us to create bacterial ‘drug-delivery’ machines or self-replicating microbial vaccines? What will the first human-created lifeform mean for our understanding of biology? Will humanity end with a ‘microbial bang’, or might microbes perhaps be the solution we need to spread our wings beyond...
