Today Earth’s population increases by two people a second. At present already more than 50 per cent of the population lives in towns and cities. Within ten years, that proportion will reach 60 per cent and 70 per cent by 2050. In 1950 that number was only just 30 per cent. The significant increase in the number of Earth’s population will undoubtedly appear in towns and cities. Urban life presents more significant challenges for urban planners, decision-makers, and societies ever (Jászberényi–Munkácsy 2019). Today a mere 150 cities provide 50 per cent of the world’s GDP. Towns and cities use two-thirds of the world’s store of energy, they are responsible for 70 per cent of total gas emission causing the greenhouse effect, and that is where 60 per cent of water resources are used up. Based on current tendencies, there will be 900 million vehicles in traffic in China in a mere twenty years, with 1.4 billion inhabitants. That is more than the number of cars that are running today on the roads of the world. Nevertheless, merely calculating with the present growth rate by that time, there will appear 2.3 billion motor vehicles, and in 80 per cent on the roads of developing countries. Today already, Beijing spends an annual $3.5 billion to manage the health damages caused by air pollution; in Jakarta, traffic jams cause 3 billion worth of damages – just to mention two severe social and economic problems. (de Miaranda–Powell 2013) Today at the dawn of the so-called fourth industrial revolution, or Industry 4.0, issues of production transformation, urbanisation and mobility (e-mobility, sharing systems, autonomous cars), cyber-physical systems, intelligent solutions, big data, IoT (Internet of Things), technical and economic transformations, the global innovation competition and its social effects are factors affecting the everyday life of individuals (and visitors). Historically, all previous industrial revolutions had significant structural effects on the economy, the whole of society, everyday customs, and in all probability, the same will happen during the fourth industrial revolution (Zsigmond 2020). Indeed, several further macro-trends generally affect the museums’ line of duty and social role. Nowadays, in the discourse between the museum and society, it is hard to evade subjects such as social problems, poverty, unemployment, inequalities in income, migration, challenges of globalisation, urbanisation, climate change, political instability, pandemics. To a certain extent, those are the questions that urged ICOM (International Council of Museums) to put on the agenda at its 2019 general assembly in Kyoto the reconsideration of the museum as a notion (Sandahl 2019). In the end, due to several reasons, the participants did not change the previously created definition of the museum, but the phenomenon in itself is remarkable when we speak about issues concerning the future of humankind and the changing role of museums. (Naturally, during the debate on the definition, several other issues came to light, but the specification of the finally unaccepted change is not the subject of this writing.)
