How have digital technologies affected the market logics and economization that constitute the underlying governing rationality of neoliberalism? This essay unfurls five theses that further develop the concept of technoliberalism, the intensification of neoliberalism through computational technology, in the context of the networked public sphere: (1) technoliberalism names the dominant governing rationality in cultures where digital computation technology suffuses everyday life; (2) technoliberalism replaces public, democratically accountable power with the private, technical expertise of digital technology firms; (3) technoliberalism focuses on contriving technical systems to change culture at the expense of democratic argument and deliberation; (4) technoliberalism intensifies the commodification of attention, resulting in undemocratic forms of “noopower”; and (5) technoliberalism standardizes subjectivities through grammatization. Each thesis complicates the prospects of democratic deliberation in the networked public sphere and articulates lines of communication research necessary for keeping democratic practices vibrant.
