I find it incredible that someone can code up a strategy for deploying an investment vault, the community, which operates as a Decentralized Autonomous Organization (DAO), can decide to vote on it, and two days later, people can start investing money into it and earning interest - no middleman or manager involved. The investment vault will deploy the capital in different protocols based on the strategy outlined (and voted on by the DAO) automatically.

The automation smart contracts can bring about is scary.
