Marc is currently a Digital Ethicist (Research Fellow in Digital Ethics) at the Centre for AI and Digital Ethics, The University of Melbourne, Australia. He is interested in the intersection between technology and philosophy... in particular, how (A) existential philosophy is relevant in the age of online social networks and social media, and (B) how technologists can optimise for human flourishing (and not for arbitrary standards of efficiency). (As an existentialist, he exercises his freedom by abstaining from Twitter by choice.)
