Is Web3 a real thing?

So, let me get this straight. You're saying that Web3 is not just a buzzword, but an actual, tangible thing that's already making waves in the tech and finance industries? Can you elaborate on what Web3 really is and how it differs from what we currently know as Web 2.0? I'm curious to understand the potential impact it could have on the way we interact with the internet and how it might revolutionize the way we do business, especially in the realm of cryptocurrency and finance.
