- Just as I am the father of two teenagers, aged 14 and 16, and although they protest against it, I must responsibly say that we should follow the example of Australia, recently Denmark, Prime Minister Mette Fredriksen, as well as France, Greece, and many other sensible countries. Sooner or later, everyone will follow this path. I call on those in power to ban smartphones until a certain age, perhaps 15 or 16, in Polish schools, and to impose restrictions on smartphone use. They truly make people dumber to a large extent, and their use in schools degrades the entire learning process - said Mateusz Morawiecki during a Q&A session.
