Yeah I agree. And sometimes it is not really the complexity. For example, kernel or compilers are very complicated in certain way, too, but whichever company makes those products probably is way more stringent about the quality comparing to other companies that are happy to move forward with tons of bugs and tech debts.

IMHO, the complexity of kernel and compilers is usually more justified and less accidental. At least non technical people are rarely the cause.
