Oh, I think one can so argue. Social media as in "public or broadcast-to-all-'friends' style posting, that pushes content at you in a way designed to maximize engagement above all other concerns", yeah, that stuff's digital asbestos. I'm not gonna take my kids gambling, either, and certainly not going to let them do it on a regular basis. Social media's just as low-value and dangerous.

Texting and equivalents, sure, not so much.
