History and Evolution

The concept of a helpful, automated assistant dates back decades. Early attempts at creating artificial intelligence (AI) focused on rule-based systems, capable of performing specific tasks based on predefined instructions. ELIZA, developed in the 1960s, was one of the first natural language processing (NLP) computer programs capable of engaging in conversation, albeit a limited one. However, these early systems were brittle and lacked the adaptability of modern VAs.

The real evolution began with the advancements in speech recognition and machine learning (ML) in the 21st century. Apple's Siri, launched in 2011, is often credited with popularizing the modern virtual assistant. Following Siri came Google Now (later Google Assistant), Amazon Alexa, and Microsoft Cortana. These VAs leveraged cloud computing, big data, and increasingly sophisticated AI algorithms to provide more comprehensive and personalized assistance.

The initial focus was on simple tasks like setting alarms, making calls, and playing music. Over time, VAs have expanded their capabilities to include complex tasks such as managing calendars, sending emails, controlling smart home devices, providing information, and even making purchases. The rise of Artificial Intelligence has been instrumental in this progression.
