Dr Ariel Zeleznikow-Johnston is a neuroscientist at Monash University, Australia, where he investigates methods for characterising the nature of conscious experiences. In 2019, he obtained his PhD from The University of Melbourne, where he researched how genetic and environmental factors affect cognition. His research interests range from the decline, preservation and rescue of cognitive function at different stages of the lifespan, through to comparing different people’s conscious experience of colour.By contributing to research that clarifies the neurobiological, cognitive, and philosophical basis of what it is to be a person, he hopes to accelerate the development of medical infrastructure that will help prevent him and everyone else from dying.

Ariel's eucatastrophe envisions a future where brain preservation technologies are fully integrated into the medical system. This would allow individuals nearing the end of life to choose preservation at a critical stage, with the possibility of future revival. Hospitals and hospices would incorporate advanced brain preservation facilities, storing preserved individuals in dedicated warehouses. Ariel imagines a future where the political will exists to develop and implement these technologies at scale, ensuring affordable and accessible procedures for all who elect to use them. With this system in place, the cost would be manageable, around $10,000 per procedure and a few hundred to a few thousand dollars for annual storage. This vision represents a hopeful convergence of technology, healthcare, and societal support.
