This may not come out as a link when posted, http://uk.businessinsider.com/former-facebook-exec-chamath-palihapitiya-social-media-damaging-society-2017-12?r=US&IR=T
but anyway search for Chamath Palihapitiya Stanford speech and you will find that “a former Facebook executive, said during a November interview at Stanford that social networks were “destroying how society works.”
If you get the full interview, the crucial bit is from 21min 22 to 26 min 40 sec.
“people are rewarded by thumbs-up signs ”
I normally just grumble into my beard, but it’s nice to have such company
