Web3 is just a subset of a much broader and profound global movement: digitization and decentralization of everything.
The most important innovations of the last 50 years were steps toward these two macro trends, such as Personal Computers, the Internet, Mobile, Cloud Computing, Social Media, Enterprise Software, Cryptocurrencies, NFTs, and so on.
Everything is going digital.
Media, buying, sales, (remote) working, dating, maps, traffic, learning, investing, entertainment, finance, money, politics, music, meeting, knowledge (wiki), (crowd)funding.
And soon housing (3d printing), healthcare (AI, Gene Editing), travel (metaverse), government (DAOs), security (AI drones), and a lot more.
Trying to decouple Web3 from the rest of the digital revolution is a huge mistake because they share the same principles (neutrality, openness), and are trying to solve the same root problems: unfairness, lack of transparency, inefficiency, concentration and asymmetry of power, exclusion, and political/financial/social privileges.
Yes, Web3 ushered in powerful and incredible new technological primitives allowing us to accelerate the climb toward a more decentralized and digital world, and it is very important to understand each one of them.
However, if you are really serious about getting Web3 right, the very first step is to understand the Internet itself, its phases, and its implication on society.
