The book "Flow", by Mihaly Csikszentmihalyi, seems to be approaching classic status among the many disciplines that are seeking a better understanding of the experiential (subjective) side of human activity. These include the designers of our digital media, who are now in the business of designing our "experiences."
To stereotype the "flow" mode of experience - as many appear tempted to do - to "flow is good" is a bit like saying "if it feels good, do it". This only makes sense as a corrective to an overly-controlled and analytical life habit, not as a categorical good. Flow is as common in addictive and destructive behavioral traps, as it is in healthy and creative states of absorbed focus.
Useful as it may be, this "in the moment" ethos is missing a perspective on ethics, and on long-term mental health.
Soojung-Kim Pang, author of the Contemplative Computing blog writes:
I think if anything has changed since Flow appeared in the early 1990s, it's that we've had a couple decades' experience with industries that have learned how to get us to have experiences that feel like flow, but aren't. They tap into our desire for challenging, engaging experiences, but don't deliver the moral rewards or self-improvement. The qualities that make flow powerful and redemptive can also make its manufactured versions dangerous and self-destructive.
