Web 1.0 referred to the original implementation of the World Wide Web in the late 1980s and early 1990s, which allowed users to view and read web pages but not interact or collaborate. Web 2.0 emerged in the early 2000s and emphasized online collaboration and sharing among users through social media and user-generated content. Speculations about Web 3.0 envision the web becoming more intelligent and personalized through technologies like machine learning, natural language processing, and autonomous agents.
