Toxic forms of public communication have become the foci of research in the last decade, particularly in the last five years. Here, we can think about misinformation, hate, denialism, conspiracy theories–all forums that we can cluster as toxic forms of communication, from a perspective that believes in public life and democracy based on understanding, tolerance, difference, evidence, data, some kind of reason, some kind of positive emotions, empathy, understanding. And I don't think that we have an (in detail) understanding of how better forms of communication can actually work in today's digital societies. We understand why toxic forms of communication have traction, why certain publics find it appealing, what are the political consequences, why social media platforms are built in such a way that appeal to the bad angels of our nature, so to speak. I don't know, if we find especially at a large scale, how the more positive ways of thinking about communication can actually be scaled up. In fact, we have a wider and richer vocabulary to call undemocratic forms of communication. We still have the same language about positive forms of communication that build democracy or democratic values. And that, to me, is a big challenge. Again, it's not about whether it works in certain specific contexts, local communities, it's how you think about large-scale phenomena here. That, to me, is one of the main challenges.
