"Creating a knowledgeable public requires at least some workable signals that distinguish truth from falsehood. Fostering a healthy, rational, and informed debate in a mass society requires mechanisms that elevate opposing viewpoints, preferably their best versions. To be clear, no public sphere has ever fully achieved these ideal conditions—but at least they were ideals to fail from. Today’s engagement algorithms, by contrast, espouse no ideals about a healthy public sphere."
"By this point, we’ve already seen enough to recognize that the core business model underlying the Big Tech platforms—harvesting attention with a massive surveillance infrastructure to allow for targeted, mostly automated advertising at very large scale—is far too compatible with authoritarianism, propaganda, misinformation, and polarization. The institutional antibodies that humanity has developed to protect against censorship and propaganda thus far—laws, journalistic codes of ethics, independent watchdogs, mass education—all evolved for a world in which choking a few gatekeepers and threatening a few individuals was an effective means to block speech. They are no longer sufficient."
