I get what you're saying but installing asbestos correctly is much easier than writing an app that could have security implications in C, is more easily detectable where things go wrong and it affects less people if things go wrong.
replyAnd the people using asbestos in their homes, or buying homes with asbestos, are endangering themselves. How likely is that an improperly installed or maintained asbestos is going to affect a whole neighborhood?
If the neighborhood was all built around the same time or by the same developer, I would say high
replyBut the people in each house would suffer from from asbestos in their own house. [0] If I bought a house in such a neighborhood, I'd have it checked from cracks or deterioration. If the results show a risk, I'd inform the neighboring houses, too.
replySimilar to how if you're using a insecure program written in C, whoever finds the bug should tell you immediately - don't use that program.
[0] You might say that asbestos from 1 house would affect the whole neighborhood but that would be similar to how a smoker smoking in the streets would affect the neighborhood. Second-hand smoking and second-hand asbestos are bad but they're negligible compared to living with a smoker who smokes indoors with the windows closed or smoking yourself.
