Smart contracts:
The basic problem is that the code is the ultimate authority — there is no adjudication protocol — so if there’s a vulnerability in the code, there is no recourse. And, of course, there are lots of vulnerabilities in code. To me, this is reason enough never to use smart contracts for anything important. Human-based adjudication systems are not useless pre-Internet human baggage, they’re vital. – Smart Contract Bug Results in $31 Million Loss, by Bruce Schneier

Fortunately for DAO investors, a waiting period for the withdrawal of funds was programmed into the Smart Contract, which the hacker had to abide by before they could exchange their stolen Ether into offline currency. This gave the DAO investors precious time to find a solution to save their investment. – The Failure of The DAO: Should We Regulate Cryptocurrency
