Technological obsolescence refers to the process by which a technology becomes outdated or no longer useful due to advancements in newer technologies. This can happen when a product, like a smartphone or computer, is replaced by a more efficient or feature-rich version, making the older model less desirable or functional. Obsolescence can also occur when a technology is no longer supported by its manufacturer, such as when software updates cease for an older operating system. As a result, users may face security risks or compatibility issues, prompting them to upgrade to newer alternatives to stay current and secure.
