By the 1990s, computers had become commonplace in developed countries, though fears about their potential impact on privacy grew with the rise of the internet and social media. Easy access to social media over smartphones helped young protestors in Tunisia and Egypt organize to challenge their governments. The movement spread across the Middle East in the form of the Arab Spring. Some nations such as China have since blocked the use of many social media platforms.         

Medical scientists have made great strides in curing and preventing diseases. Vaccines eliminated smallpox around the world and came close to eliminating polio. But new illnesses arose, including Ebola virus and HIV/AIDS. Since it was identified in the 1980s, treatments have emerged to make it a manageable disease for many rather than a lethal one, though in the developing world, it is still a huge problem. The most recent challenge to world health, the COVID-19 pandemic that began in December 2019, demonstrates how both globalization and technological developments affect life in the twenty-first century.
