Humans aren't addicted to social media; they're addicted to being social. Social media just gives us a relatively safe space to quell those social desires with groups more like-minded than could be easily found offline.
So, to answer your question, we'll get over our social media addiction when the next, more addictive thing comes along... probably a device to allow us to upload our thoughts to the internet in real time with an ML algo to choose which thoughts are post-worthy and which thoughts go straight to the ad network for "more relevant content".
