Surely an issue here irrespective of technology flaws or not is the economic impact on the time taken to write smart contracts. If it now takes substantially more dev time to write a smart contract that is "secure" (ie by spending lots and lots of time testing for vulnerabilities) this will invariably come at a cost. So while the theory of smart contracts is brilliant this recent hack might go down in history as a case study as to why writing contracts is too expensive to do in all but the top 1% of situations.
