At its worst, the web is a putrid miasma of neo-Nazi trolls, misinformation and AI-generated slop; at its best, it shreds our attention into little scraps. The question is not whether online life is wretched—it is—but whether it was always so depraved, and whether its depravity is a fait accompli. Tim Berners-Lee, the inventor of the World Wide Web, doesn’t think so . . . it doesn’t have to be this way, he insists. The web was once a tolerant, welcoming and slightly anarchic place, and Berners-Lee assures us that it can be salvaged yet. He is such an affable, avuncular narrator that I am almost tempted to believe him.
