I agree with him, but I think there are multiple different ways to approach this issue (in many western countries).

Part of this is starting boys one year later in school, because developmentally, boys hit puberty later than girls. Another part needs to be offline activities like camping, biking, and sailing that get boys outside and playing with each other in healthy environments. Scouting was a great example when I was a kid. It let kids blow off excess steam, while teaching them how to work together, how to safely help injured people, deal with emergencies, and experience the wonder of the outdoors. It also taught good skills like swimming, personal finance, and leadership.

I think back then, the Internet was a lot more rudimentary, and cellphones really could only be used for calling. Videogames were collaborative, in-person activities, and while it did peel people away, it wasn’t the isolated, single-player experience it is now. Kids and adults have to get away from that sometimes.
