A lot is made of the Like button, of the societal impact of the dopamine-inducing blue thumbs-up. But as a generally reserved social-media poster, and only sporadic "liker", I am relatively indifferent.
Far more sinister, in my mind, is the infinite scroll, and its auto-play video cousin - on Facebook, Twitter, YouTube and friends.
Not because of the clear connection with the culprits' business models - where eyeballs and time spent drive ad impressions, which drive revenue. That much is understandable - these are publicly listed companies.
I think the problem I have is that it is playing on a particularly human vulnerability, evolving as we did in a world of scarcity, rather than abundance. Where evolutionary pressures favoured repetitive behaviours, as in general things would run out. Make hay while the sun shines, because at some point autumn will come.
But on the endless tracts of social media the sun is always shining, without respite. And instead of introducing patches of shade, where travellers might rest, or step away from their smartphones, our social media overlords have built a desert, where users stagger towards an imagined oasis that never comes.
Meanwhile the new demi-gods of TikTok have learned their predecessors' worst habits, as video after snack-size video plays off into the distance.
We are in the dog days of the digital summer. The onus is on us as users to find shelter, or to escape the desert altogether.
