I mean, yeah - that's why it's so valuable. When something is so rigorously guaranteed that it's almost absolute, it's able to change your behavior, dramatically. It's incredibly liberating. It's like turning on the water tap, and never fearing that you're about to drink something toxic. You can do things quickly and casually, because you know you've got a solid bit of "terra firma" to stand on. If we didn't have things like this, we couldn't have i.e. airplane travel. It's absolutely commendable for them being at such a high watermark for reliability, but - much like a doctor saving sick patients, or the mail service delivering letters, aspirationally speaking "nothing less than perfection is acceptable".
