Every time I read the story of Therac-25 I feel incredibly frustrated AECL never faced real consequences or (criminal) liability for it.

Maybe I'm retroactively imposing modern day safety culture, but reading the timeline and history, it feels like AECL was completely negligent in waving off the issue as more and more fatalities kept piling up.

Can't believe the devices weren't pulled offline to definitively solve the issue after the first death. Instead, they basically went "can't repro, oh well".
