Billions of germs surround us every day. We have developed a sophisticated biological defence system, the immune system, to keep us functioning. However, we are also surrounded by several digital germs that can lead to illness. We are currently experiencing an extreme radicalization of digital germs: Fake news, racism, sexism, cancel culture, ghosting, and more. Unfortunately, our digital immune system is not yet sufficiently adapted. Evolution takes time, much more time. So how can we intervene? Raise awareness through educational campaigns? None of this has been enough for a long time. Medical intervention against the evil of the internet and its digital-somatic consequences is essential. This is why the students are presenting ProbusA21.1.0: the first probiotic in the series of cures for digital diseases and for a strong digital immune system.
