IME, "Why systems fail" almost always boils down to a principal-agent problem. This is another way of expressing the Mungerism "show me the incentive, I'll show you the outcome".

Systems that "work" tend to have some way of correcting for or mitigating the principal agent problem by aligning incentives.

I'd also point out that hardware is a much older discipline, in terms of how long it's been operating at scale. It's had more time to formalize and crystallize. Intel is 56 years old. Google is 27.
