I would much rather rely on data on this kind of question over vibes. Efficiency means things move quicker and cheaper, and a few people get richer. It does not by any means inherently increase safety. The effects of a fuckup in a hugely efficientized industry often scale directly with just how much efficiency was mined away from caution and human-interaction.

Bubba flipping burgers getting his dirty hands on your meal might make you sick, but Bobba inspecting the meatslop production line with constant pressure from upper management to be as efficient as possible according to whatever recent regulations were stripped back might accidentally spray the horse-meat product decontaminizer on the pig-meat product, generating a national pandemic.
