My own minimal use of social media has allowed me to keep up with old friends, to share unusual online experiences, and to learn about many things like detailed product evaluations, specialized cutlery, and several forms of dance that I had never before even imagined.
There are many dangers with social media, but also great value. Anyone recommending to turn it all off because of the damage that may be done is probably missing out on a lot and propagating that blind spot with their well intended advice.
