Maybe you're trying to make the point that for very complicated systems with many failure points, the reliability of a single component is less impactful than redundancy and there is some truth to that but I must point out that risk vs cost calculations are definitely happening in both industries you mention.
Triple redundancy is not a thing in general aviation while, for some systems, it is in commercial. That's a risk vs cost calculation.
Semiconductor manufacturers do risk vs cost calculations through the entire development and manufacturing process. Source: I've worked in semiconductor, doing those calculations.
