Abstract

'Sliders' are a speculative introspection-enhancing future technology allowing humans with cybernetic brain implants to precisely and voluntarily modulate moods and other mental states that vary along a one-dimensional scale. Such future humans may, for example, use the Sliders interface to temporarily present a COWARDLY–COURAGEOUS 'slider' in their visual field, and with a mere act of will change their level of courage from a 60 to a 65 on the 100-point scale. The present article discusses the implications of such a technology in the form of an epistolary fiction in which the author's future persona warns the reader of the dire consequences and hardearned insights arising from widespread Slider use and abuse.
