I’m sorry but not going to trust an author who has a very real financial incentive to sell a hypothesis. There are indeed numerous studies that do summarize the negative impacts of social media and smartphones on mental health, and it’s also extremely true that the increase in mental health diagnosis can also, at least partially, be attributed to an increase in mental health awareness. My ADHD existed well before I got my hands on tech.

EDIT: to summarize, I don’t really take issue with your comment, but I believe that you can find an even better source of information to link to when discussing this topic. Wishing you well!
