Science fiction has explored many disaster scenarios, from the most obvious (pandemics, catastophic climate changes, etc.) to the least likely (singularity, ET invasion, etc.). In many cases, given enough time to identify the threat and to coordinate, the outcome really depends on the balance between powerful technoscientific responses and a sound political leadership to control them. So I guess that my personnal utopia would be a strong, yet democratic and benevolent, global goverment in charge both of the continued growth and sharing of human knowledge in happy times, and of its mobilization during emergencies.
But as Juvenal already knew, the People's choice to devote most ressources to offering 'bread and games' to all, '_Panem and Circenses_', regardless of disasters to come, can be a rather direct path to decadence and unability to avoid or minimize such disasters when they finally occur. Moreover, this difficulty, which might be inherent to democracy, is entangled with the degradation of language, thus of science itself. Indeed, the most relevant dystopia remains in my opinion Orwell's _1984_ and its 'newspeak' as a tool to limit individual creative thinking through the impoverishment of language and the collective focus on semantically null slogans and fallacious issues.
The present COVID crisis appears to me as a direct illustration, and as a warning : will the scientific community was able to provide relevant answers and develop efficient vaccines in record time, the lack of scientific culture among politicians (including a frequent confusion between science and medicine, even in Louis Pasteur's France) was in many countries a source of avoidable delays, of confusion (many people still doubt the usefulness of masks, encouraged by politicians) and of avoidable economic disasters (unsuitable or poorly timed lockdowns, etc.)
