Only two things change what makind does: Money and Death.
Fortunately, no one has died and it is Money that is going to change this. Companies that try to save money in the early stages (of anything) usually land up paying MORE money in the later stages.
Humans don't change much. When the report on the crash of Shuttle Columbia was published, they showed that NASA had not learned some of the lessons from Shuttle Challenger 17 years before.
