"The civic tech expert Ed Saperia used as his parable the difference between Wikipedia and Facebook. Jimmy Wales’s big experiment, which started life in 1999 as Nupedia, has created an open-source collection of human knowledge in hundreds of languages that is essentially trustworthy. If a mistake creeps in through the gates of human generosity, it gets corrected in the same way. If malicious actors try to slander their foes, the punishment is not cancellation, but more like lifelong ridicule, which is proportionate, given how long a slanderous person is likely to carry on doing ridiculous things. In other words, it is the best of humanity, all natural desire to help each other with cross-pollinated knowledge concentrated in one place. Facebook, for brevity, takes the same raw material – all the people in the world – and finds the worst in it. Facebook manages to winkle out things we didn’t know we were capable of – levels of vitriol, gullibility and hysteria – in between a scare ad for dark politics and a mesmerising video of five types of mince baked around a kilo of cheese. (I am paraphrasing a bit; I don’t think civic tech gurus dwell much on the cheese.)"
