Is Social Media a Tool for Self Expression?

I think the biggest issue i have in conversations with my grandparents to my parents, to educators is isn't it helping people understand that technology and social media a tool for self expression? And that is truly why i think a lot of teans and kids and genzi remain. It really does allow for this open canvas for me to paint and explore. But at the same time, it can turn into this harmful, parasitic relationship that is incredibly detrimental to kids and to our generation.
