When I studied ASIC design, it taught me that the complexity increases and reliability decreases every time they shrink a process node. There’s increased variation, degradation, etc. One paper on 130nm to 90nm said they had to build digital monitoring or correction when in the analog parts while cell phones were mixing in analog to save energy (mixed-signal). The point is that having the reliability of older computers might require the older, simpler hardware they were using. More breakage might be an inherent tradeoff of using modern processes, at least up to a point. I still have always wanted to see someone mix low-cost components with the older, patent-free, NonStop architectures. The desktops would look like the dual-motherboard SGI’s with pluggable CPU’s, etc. Just replace what breaks with the system chugging along using other components.
