Technology (such as smart contracts) should work for people in sustainable way. It means that technology
(with help of community) should be taking into account potential,
socially detrimental activities (such as this malicious and greedy DAO code exploit), which have no consideration towards well being of humans. Smart contract (code) should be only an ultimate law, as long as it supports activities which are beneficial for betterment of humanity. If someone tries to exploit the smart contract for selfish reasons, then community should have the right to intervene in the contract. Such technology is pointless if it does not include adaptation to human and environmental factors and works like god with ultimate, unquestionable rules which do not improve quality of our lives.
To add, in order for community to reach an intelligent, coherent and logical consensus about any voting, (democracy), it requires keeping every single participant of voting to, as informed and educated as it is possible, about the topic of voting. Democracy will never work, if voters make decisions individually instead of arriving at decisions together. Making decisions comes from ignorance. Arriving at decisions comes from knowledge. That's the difference between making decisions and arriving at decisions. Difference between illusion of democracy and realistic democracy. Such approach is highly scientific. Scientists arrive at decisions in well informed consensus after extensive and objective research (Scientific Method).
