Automation of trust is illusory.
That is the thesis form this Aeon piece on the failure of Ethereum, a popular blockchain. There are many other points of interest.
How about this question:
Why are people so eager to put their faith in blockchain technology and its human supporters, instead of in other social and economic organisations?
What it really exposed was the extent to which trust defines what it is to be human. Trust is about more than making sure I get my orange juice on time. Trust is what makes all relationships meaningful. Yes, we get burned by people we rely on, and this makes us disinclined to trust others. But when our faith is rewarded, it helps us forge closer relationships with others, be they our business partners or BFFs. Risk is a critical component to this bonding process. In a risk-free world, we wouldn’t find anything resembling intimacy, friendship, solidarity or alliance, because nothing would be at stake.
