Human nature vs cryptographycally strong algorithms

This is a phylosophycal thought coming from
recent happenings we all have read in community
space like telegram etc.
Human nature can fail and act to think about corrections, that’s
our advantage over automaton.
Blockchain automatic transaction whilst being fast, are supposed
to be fair.
There is a fraction of this speedup which shouldn’t overwhelm
the human option.
How far our steps are going to take us in delegating a social behaviour?
