> a lot of the systems we build and use just don’t need the level of reliability that e.g. a bridge needs Sure. As the saying goes, "Anybody can build a bridge that never falls down. But it takes an engineer to build a bridge that _almost_ doesn't fall down" (referring to being able to build it in a cost-conscious way). There's a spectrum there for sure, but as an industry we're on the other side of it from where I personally wish we were. We should be embarrassed that "it must have been a computer glitch" can be used to explain away nearly any problem. Because it's usually right, and it's usually our fault rather than the cosmic rays.
