I think I didn't articulate my point well. It's that complexity isn't a 1 to 1 mapping to reliability. There is plenty of complex equipment that fits your criteria. My pool pump is full of electronics, has moving parts, sits in inclement weather, and lasts for years. There is equipment that can sit near the combustion chamber of a rocket experiencing extreme g forces, pressure, and heat and survive. It can be engineered.
