This would stop the currently exponential pace of growth from outpacing what society, and regulation, can adapt to. Thus avoiding the inevitable crash that will happen when we lose control of the exponentially accelerating train of technology, and it flies off the rails.

Assume everything else, like the quality of the content, would stay the same as now

This would tell us if social media content behaves like & should be treated as a commodity (just like magazines & DVDs), or something completely different like waste or like a public good

For me there's two separate participants, a 'talker' and a 'listener'. My mind identifies more with the talker, because that's the one that has agency. Since there are two participants, both of which are me, I talk in 1st person plural ('we've got to do ...', 'we thought about this earlier'). I stopped being afraid of being alone after I started having an internal dialogue around the age of 11, since having a second participant in the conversation meant I was always in company.

Edit: Wow, looks like there's a lot more diversity in this than I was expecting
