I disagree. Risk isn't binary. Part of being an engineer is trying to quantify the risks of a given design so that anyone subjected to the platform is aware of them. If a submersible with a cylindrical carbon fiber hull fails after five or ten dives and gives no advanced indication of its impending failure, that's a much riskier proposition than a metal structure which can go hundreds of times and shows very obvious advanced warning signs.

To put it in a different context, consider when Uber was playing with autonomous driving. Their miles-driven-per-incident rate was orders of magnitude lower than any commercial fleet of human drivers or even the general population of human drivers.

Engineers have an ethical duty to try to quantify these risks and present them as accurately as possible to those who make decisions. Anything less than that is performance art.
