How crazy. I'm a big fan of Ethereum and thankfully didn't have any holdings in parity, but man, it is hard to believe a newb could destroy $100s of millions just while experimenting with some code.
Not sure why you find it hard to believe. Ethereum is Turing complete and ETH is a public blockchain. That means anyone (amateurs, incompetent coders and hackers) can run code on the system anytime they want, even unvetted insecure code. Will happen over and over again.
