Critical Reflection
In designing a speculative spiritual technology, I most wanted to ensure the plausibility that the fiction could occur realistically as Anthony Dunne and Fiona Raby explain it in Speculative Everything: Design, Fiction, and Social Dreaming. This made the most sense in the context of experiencing other Sci-Fi and thinking “Yeah, that could happen!” 
The point is to explore alternative cultural practices or shifts, rather than trying to predict the future. I chose to avoid preferability by keeping a satirical and more farfetched fictionalization which prevent assumptions of best fit for whom and government regulation.
In brief, the speculative fiction I have created is an individual implanted immunity to improve humanoid survival rate in the ever-changing atmosphere of the planet Keerotera. The science is not well understood, leading to trust issues in the implanted device. Those who wear the visible mark of the device are social, and throw many City Festivals in celebration, or communal worship, of the saving technology. Those who do not opt into immunity must isolate themselves in order to preserve their own health and to prevent any dangerous spreading.Another challenge in my design process was to create a spiritual technological device which challenged the premise of the bounds presented by ‘sacred space’ and ‘sacred time’ as explored by Benjamin J. Fleming and Richard D. Mann in Material Culture and Religious Studies. Religions and religious practices can often be strongly affiliated with physical buildings and timely rituals or celebrations.
