Capacitors would be the big concern, but they're almost always replaceable. Generally, everything has a lifespan though. I've got a keyboard that can handle 10 million presses on each key, but... that time will eventually come. The next thing would be the chips, as they age at even moderate heat levels (an average desktop CPU will handle over a million hours of uptime, even if only idling, but it will degrade). But I think you would literally have to run an ESC for hours a day over a decade before it would "wear out" the motherboard.
