Steel has almost always (as in 99.99...% of the time) delivered to our expectations based on our understanding of it.

The cases where we built something out of steel and it failed are _massively_ outnumbered by the instances where we used it where/when suitable. If we built something in steel and it failed/someone died we stopped doing that pretty soon after.

This is partly due to having a safety factor: i.e. using twice as much steel as you think you need.

Understanding means knowing the limits of your own understanding, and building in safeguards.

fire retardant, keeps the rats out. flawless performance.

people working around it get sick but lots of people get sick, why is that a problem?
