It has become almost impossible to separate the effects of digital technologies from our everyday experiences.With the help of these philosophers and their novel ideals, Stiegler began to reshape his earlier political commitment to Marxist materialism, seeking to account for the ways that new technologies shape the world.Reality is parsed through glowing screens, unending data feeds, biometric feedback loops, digital protheses and expanding networks that link our virtual selves to satellite arrays in geostationary orbit.Lyotard would oversee Stiegler's master's thesis after his eventual release; Derrida would supervise his doctoral dissertation, completed in 1993, which was reworked and published a year later as the first volume in his Technics and Time series.This is Stiegler's legacy.
