I spent 5 years in nuclear power before going into tech and I have sort of joked that the software engineering the goes into AI, IoT, Phones, Cars, etc, is the next Chernobyl waiting to happen. It's all fun and games till these things get connected directly to lives. I actually find the governance of nuclear power a decent model for managing the risk. You mentioned management needs to be held responsible but management will choose short term profit every day until dealing with negative externalities is forced upon them like it is in nuclear.

Imagine if the toxic waste that is the mental impact of social media, or forever insecure devices littering the Internet, or any number of things was obligated to the companies to do their best to fix it. Nuclear reactors put huge money away so that when they are done they are bulldozed back into a green field (Other than what was supposed to be a solved problem of spent fuel).

Anyways, the likelihood of regulation is nil and a global world means those negative externalities will continue on churning till the world agrees we suck at managing risk. Which is also nil. Mental health crisis and insecure tech just isn't as flashy as nuclear in terms of getting regulated in the interest of public health.
