When the threat posed by the digitalization of our lives is debated in our media, the focus is usually on the new phase of capitalism called “surveillance capitalism”: a total digital control over our lives exerted by state agencies and private corporations. However, important as this “surveillance capitalism” is, it is not yet the true game changer; there is a much greater potential for new forms of domination in the prospect of direct brain-machine interface (“wired brain”). First, when our brain is connected to digital machines, we can cause things to happen in reality just by thinking about them; then, my brain is directly connercted to another brain, so that another individual can directly share my experience). Extrapolated to its extreme, wired brain opens up the prospect of what Ray Kurzweil called Singularity, the divine-like global space of shared awareness … Whatever the (dubious, for the time being) scientific status of this idea, it is clear that its realization will affect the basic features of humans as thinking/speaking beings: the eventual rise of Singularity will be apocalyptic in the complex meaning of the term: it will imply the encounter with a truth hidden in our ordinary human existence, i.e., the entrance into a new post-human dimension, which cannot but be experienced as catastrophic, as the end of our world. But will we still be here to experience our immersion into Singularity in any human sense of the term?

Existential anxiety is an outstanding issue both in psychology and philosophy. It implies the mental rummage following the notion of existence, inexistence and related concepts. Martin Heidegger is a philosopher incorporating the meaning of existential anxiety and time perception in a unique comprehensive view, suggesting that there is a relation between being, time and anxiety. To the best of our knowledge, no empirical study has assessed any association between time perception and existential anxiety. The current study aims at investigating the mentioned association. Eighty four students in Tabriz University of Medical Sciences voluntarily participated in this study and gave their written informed consent. Time perception was assessed by verbal and production tests. The score of existential anxiety was obtained by the Good & Good Existential Anxiety Questionnaire. Association of time perception and existential anxiety was analyzed statistically. Mean score of existential anxiety of subjects was 7.57±4.75 out of 32. Accuracy of time perception was significantly related to existential anxiety score ( P = 0.034); in the manner that inaccurate time perceivers had higher existential anxiety scores. The results of this study are preliminary in line with the existential concepts presented by Heidegger; indicating that existential anxiety and time perception may have common roots. This understanding about existential anxiety suggests further explorations and deeper existential reasonings, as well as more efficient psychological and psychiatric clinical practice.
