Blockchain and decentralized applications

Crypto is so daunting to people because there's too much hypothetical, hyperbole, and jargon. The best way to understand is through example. What is 1 specific example how crypto/blockchain tech is offering a 10x solution or an entirely new solution to a problem?

After 18 days of diving deep into crypto, I didn't come out of it a decentralization maxi. There's space for both types of software, community, and utility. In many ways decentralized software really needs centralization: spam, fraud, content rights, powerful programs, etc.
