In 2017, the writer Mark O’Connell published a book about the transhumanist movement, To Be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death. Encountering an extraordinary set of people keen to use technology to push the human body past its physical and mortal limits, Mark explored the scientific and ethical questions behind a quest to free human beings from our corporeal cages. At last year’s Dublin Theatre Festival, Mark, along with directors Bush Moukarzel and Ben Kidd, premiered a theatrical adaptation of his book. At Ireland’s Edge, Mark and Bush spoke to Síobhra Quinlan about turning this unusual book into an even more unusual play. Their discussion begins with an excerpt from To Be a Machine (Version 1.0) starring Jack Gleeson.
