Humans are irrational. We also value "feeling" safe. Some tricks sell the illusion for those people who can't trust 100% some technologies.

Of course I trust engineering, I know planes are safe: but when there is turbulance and I see a flight attendant just casually walking and not even reacting to it, I feel better.

Humans are still humans.

Of course, culture changes. Colective ideas and institutions adapt. But extremely slowly compared to advances in tech.
