Almost everything. While UNA Europa appreciates and celebrates the heritage of old institutions, it is tempting to throw away everything we know about universities and start over: if you founded a university in 2025, you would not design it the way universities look today. Lectures emerged when books were scarce; now knowledge, data and information are everywhere, so discussion and engagement are the real purpose. Classrooms could give way to informal encounters and conversations over coffee — more collaborative and engaging, the way many schools have been redesigned for children. Young adults can still play, too: a playground at the university, freer exploration, fewer fixed learning objectives for every class — and more colour, more couches and free coffee.
