Smart contracts and transactions are seen as the blockchain transforming the whole process of buying and supplying services. Stripping out cost and greedy third parties that charge too heavily for trust in contracts. 

You'd think that after 8 years or so a critical blunder like this would not happen. 

Commerce, finance, insurance, banking, consulting all rely on rectification of mistakes, reconciling of misunderstanding and the application of the principle of "reasonableness" in law.

Looks like Blockchain has some major questions to answer!  Not to mention Parity Technologies.
