This book is a must-read. It covers many reasons why our attention spans have been degrading over the last few decades, a substantial chunk of which is due to corporate social media (personally, I think the jury is still out on whether other forms of social media can be beneficial) If you care about your personal mental health, or global geopolitics, or climate change, I'd strongly suggest reading it. The book covers a lot of ground, includes a lot of research, and has an excellent systemic analysis (instead of the usual individualistic focus of self-help books). It's also an enjoyable read.
