No moving parts, small and stable voltages, relatively stable temperatures, no capacitive sections to experience electromechanical strain. There's essentially nothing that can "wear out" in a CPU. Basically the only things that can degrade a CPU are if you run it on a noisy voltage source (unlikely, behind a power supply), or if you regularly turn it on and heat it up a lot and then allow it to cool. But if you keep a CPU well cooled or just run it constantly it will last essentially forever.

This isn't true. Aging is now more of a concern at 16/7nm to the point there's extra margin specially for it. But all that margin does is delay the impact beyond the realistic lifetime of the chip (normally approx 10 years for consumer stuff). Sometimes you can't afford the extra timing margin and you have to use extra anti-aging circuitry instead.

There's electromigration which is harder and harder to mitigate with smaller process nodes
