The DAO hit every objection from smart contract skeptics, bang bang bang - legal code doesn't work at all like computer code, immutability means you can't fix mistakes, immutability means you can't deal with changes in circumstance, immutability means you must code with 0 bugs - but even we were surprised when they went "lol immutability guarantee" the second the big boys were in danger of losing money.

It's almost as if software technology can't magically solve problems inherent in the flawed nature of humanity.

That's a strawman of what GP said. Of course technology can't solve humanity's flaws. The point was that smart contracts caused many problems they weren't meant to, which was exemplified by the DAO hack. Smart contracts failed to deliver on their promise and the fallout proved that when it came down to brass tax, nobody with skin in the game would respect a smart contract's execution anyway.

FYI the term is "brass tacks" not "brass tax"
