I feel the same too. And I believe there is much more complexity in the question "will this be good for society overall" than technologists can apprehend. For example even though I recognize some benefits to social media, I'd have a hard time arguing that on a societal level it's not a huge net negative. Overall, people are more divided, more angry, depressed, egotistical because of social media and the attention economy. And ultimately, as one of my previous boss would say "it's all about people".
