These things are so useless. For one they are not legal contracts, they are instructions the entire network must execute in a limited VM, and the instructions really can only trust the blockchain, so the outside world is continuously shoveled on the blockchain by oracles as if they are infallible, but they are not even properly incentivized to provide correct or valuable answers. You end up paying a fortune for trustless consensus even though what ends up on the blockchain itself cannot be trusted.
