Modern appliances and vehicles have made life more convenient by reducing the effort required for tasks like cooling, refrigeration, cooking, and transportation. Entertainment media like movies, music, and television provide ways to past time. Medical advancements have increased life expectancy through treatments, surgeries, and medicines. While technology has benefits like sharing information online and increased connectivity, it also enables terrorism and pollution, reduces real-world interaction, and can promote addiction and laziness if overused. Both benefits and drawbacks exist, so it is difficult to definitively categorize science as purely good or bad.
