Yeah, I think a lot of the "hardness" of hardware is of a different flavor than software. The author mentions how many lines of code are in the software, but that really is more of a symptom of something that makes software "easier": you have way more flexibility to iterate, and try new things, at a relatively low risk and cost, even if it's embedded software (at least for non-critical applications). Hardware is just more unforgiving. There's no cheap way out of the kind of scenarios you mention.
