Blockchain and decentralized finance are incredible, and open the door to a lot. There are stupid people who treat it as just a place to speculate, but it's much more than that ...
The concept of having a completely public, immutable, unbreakable record, without depending on any kind of authority is AMAZING.
One thing I think is really cool is that automation usually only happens at the worker level, eliminating the jobs of people who have been thrown down by capitalism.
But blockchain is an example of automation that takes away one of the main functions of the guys up there! Banks, and other powerful entities that manage to control the economy and manipulate governments with it.
