And we sort of understand that halfway. The arrow of time is based on ideas that go back to Ludwig Boltzmann, an Austrian physicist in the 1870s. He figured out this thing called entropy. Entropy is just a measure of how disorderly things are. And it tends to grow. That’s the second law of thermodynamics: Entropy goes up with time, things become more disorderly. So, if you neatly stack papers on your desk, and you walk away, you’re not surprised they turn into a mess. You’d be very surprised if a mess turned into neatly stacked papers. That’s entropy and the arrow of time. Entropy goes up as it becomes messier." Sean Carroll (theoretical physicist at Caltech)
How did Ethereum Betray the Arrow of Time
Ethereum turned back time on the DAO attack. While it may be nice to think about a world where we can turn back time and simply hit undo the ramifications of our actions are real they play an import role in our experience of the world, our sense of morality and community. The whole process in all directions as far as we can extend our sights into the depths of space is based on the passing of time. To betray the simple principle of the passing of time and its finality means that Ethereum has betrayed physics and our understanding of how every part of the universe behaves.
Why this actually makes Ethereum Useless
Ethereum use cases are mostly a huge liability for the network and token holders. Some think that implementation of Fiat currencies or Amazon dollars that use Ethereum will make its value go up however I think it would be a very short time before we saw situations similar to the DAO attack. How can Ethereum be used to represent Gold or Real Estate if those things which cannot be physically reversed in time can be digitally reversed in time. Nobody wants to go to the bank to find out their transactions have been reversed. A smart contract is supposed to be a promise, the DAO was supposed to be a promise but it got broken. Friends dont break their promises.
