Social media is this generations asbestos.

All social media has done is serve to remove people from their real life communities because of it's never ending nature. The end product has been deliberately designed to extract as much time from the user as possible. Tiktok is the worst of these platforms for it.

Prior to social media we had healthy online communities based around interest forums. These were segregated so fringe elements stayed at the fringe and truly decentralised because anyone could build one on their guestbook.
