And let's not forget the decades it then took to overcome the lobbying of the tobacco industry. Same thing with climate change, people have been writing about the perils of messing with the greenhouse effect for a good century, yet, here we are. So, let's say that at some point there is conclusive evidence that social media have costly negative side effects on society and its people. What then would the multi-billion dollars company behind this do about it? As much as cancer-free cigarettes or CO2-free combustion never really were an option, given the possibilities of the digital world, I still hope there are ways to use technology to have an overall positive influence. Nonetheless, with the same kind of sad stories that never fail to repeat themselves, I feel like there's a fundamentally deeper issue at work and I genuinely wonder, how would you, could you, "hack the system", so to say, and use all its dirty mechanics so that the pursuit of private interests would, for once, have positive externalities?
