I think we have moved past that expection that a personal computer, a mainframe or electronics should last 30 years. If you need a system that's reliable for decades (like a pension system), you probably should also think about how are you going to keep the system running after the current hw arch is discontinued and people knowing the specific programming language are retiring. Nostalgia is great but I don't really care if my intel pc that I replace once a year lasts for 5 years or 30 years.
