Found it. I keep recommending this book on this community. :)

From ADHD 2.0:

Modern life compels these changes by forcing our brains to process exponentially more data points than ever before in human history, dramatically more than we did prior to the era of the Internet, smartphones, and social media. The hardwiring of our brains has not changed— as far as we know, although some experts do suspect that our hardwiring is changing— but in our efforts to adapt to the speeding up of life and the projectile spewing of data splattering onto our brains all the time, we’ve had to develop new, often rather antisocial habits in order to cope. These habits have come together to create something we now call VAST: the variable attention stimulus trait.

Whether you have true ADHD or its environmentally induced cousin, VAST, it’s important to detoxify the label and focus on the inherent positives. To be clear, we don’t want you to deny there is a downside to what you are going through, but we want you also to identify the upside.

I do suspect that we're likely already seeing a spike in VAST since a bunch of kids with growing brains did online-only learning for a few years during the pandemic instead of sitting in classrooms learning to focus on something not screen related...

We love How to ADHD! The doctor that diagnosed my husband recommended it to him, and we’ve started watching. Just gotta find the right ones that my BIL will be receptive to. Thank you!
