What the heck is Web3?

So, I've been hearing a lot about Web3 lately, but I'm still not entirely sure what it is. Can you explain it to me in simple terms? Is it just a new version of the internet, or is there more to it? How does it differ from Web2, and what kind of impact could it have on the world of cryptocurrency and finance? I'm really curious to learn more about this emerging technology and its potential implications.
