What is an acceptable risk?

The difference between the risk analyst’s idea of “acceptable risk” and the public’s is similar to the difference between a physicist’s idea of “work” and the colloquial meaning.

“Acceptable” in this case does not mean okay or good. It only means that temporarily, continued investment in risk mitigation may no longer be the top priority in comparison to other risks.

As other risks are mitigated, then a previously accepted risk, may once again, become unacceptable.

Individual risk can be small while collective risk is still significant

“The odds that you will win the lottery today are tiny — but the odds that nobody wins the lottery is a whole different bet,” Mr. Muelhaupt said. “And that’s the thing.

We can investigate how AI/ML models work

I get and agree with the concern here, but this idea: “You can’t cross-examine an algorithm…. It’s a black box.” is false. To effectively use ML/AI, we have to do this, and we can, though it requires careful work. | https://vox.com/recode/2019/10/20/20921354/ai-algorithms-essay-writing
