My random conjure if anyone cares:
I see it like many ‘real’ medicines that alleviate symptoms. Sometimes the symptoms are the ones causing the issues, EX. a fever to kill germs can kill braincells. But like any medicine that alleviates symptoms, it can also hide problems. So I see it as a case by case thing.

I like Snapchat, it encourages video communications really well. Of course many other platforms have video, but the fact that by default, there’s not going to be a saved log of you being dumb on video really gets people to engage. I know it’s possible to save snaps and other platforms have a ‘delete after’ option for video. But Snapchat just makes it so easy to send a dumb snap to a friend and really inconvenient for them to share it with someone you don’t want.
