A semi-related thought I've had recently:
I've run into a number of non-technical product people that say that they're primary skill is that they have a great "product sensibility" that engineers lack so they need to step in and provide guidance. It's true that many engineer-designed products are terrible, but I'd argue that most engineers have pretty good product sense.
The problem is that engineers have a conflict of interest that leads to them making sub-optimal product decisions. A non-technical product person gets the "luxury" of only thinking "what is the best product for the user?", so they end up with a good design. But an engineer can't help but also factor in "i'm the one that has to build this, so how much extra work am i giving myself?" so they're design will be a compromise of what's good for the user and what can be built easily.
this can have big consequences for how an org should divide work. If somebody has a broad set of responsibilities, they can't help but make tradeoffs (that they might not even be cognizant of) because they're weighing multiple objective functions.
So, when it comes time for figuring out who should be in charge of strategy, it might not just be an issue of "who's better" but more an issue of "who has the least conflict of interest"
