We test medicines for side effects. Why not technology?

Every medicine comes with a warning label. Before a new drug reaches the public, it must pass years of testing. Researchers examine not only whether it works but also whether it causes harm. Regulators demand evidence. Pharmaceutical companies are expected to prove that their products are reasonably safe before people use them. Technology, by contrast, has no such step-by-step testing procedure. A social media platform can decide how billions of people communicate. A smartphone can alter daily habits across entire societies.
