Agreed that new technology takes a while to de-bug. With anything to do with civil aviation it takes a while longer than in the military, where they can afford higher risks.
When we got the first civilian jets (Comet etc) there was a spike in accidents, but within a few years they became infinitely safer than the old clunkers they replaced. Today we would not accept the risks that were taken with those early jets, so yes, it will take maybe 25 years and so meantime we will need to deal with imperfect humans occasionally having major brain farts.
