# Sliders **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 eld, 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 ction in which the author’s future persona warns the reader of the dire consequences and hard-earned insights arising from wide-spread Slider use and abuse. Hello from the future. I write with a dire warning. Never mind how, or from when, for none of that matters. I hardly understand it myself. Just trust me when I say that we've solved all of the time-travel paradoxes you can think of, plus a few more. But do understand this. Despite the vast powers we future humans have at our disposal, a horrible doom awaits future humanity unless past humanity, you and your contemporaries, act immediately to avert it. And that terrible doom bears this simple name: "Sliders" "Sliders" is what we call the number-one all-time most popular app for the braincomputer interfaces that each of us future humans have implanted in our brains.
