How did the internet start, how has it evolved, and what makes Web3 and blockchain different from the internet we use today?

I would like to understand the full story of the internet from its origins to where it stands today. How did the internet begin, who invented it and what was it originally designed for? How did it evolve from a military and academic network into the global commercial web we use today? What are the defining differences between Web1, Web2, and Web3 and what problem is Web3 trying to solve that the current internet cannot? How has the internet transformed humanity for better and worse, including its impact on communication, education, commerce, democracy, and inequality? What are the fundamental weaknesses of today's internet, such as centralisation of power in the hands of a few large companies, data privacy concerns, censorship, and the digital divide? And what does blockchain technology actually change about how the internet works at a structural level, and is Web3 delivering on its promises or falling short?
