This rating is at 105degC. Assuming your capacitor runs at slightly elevated temperature of 45degC it will last over 50 years (since life of capacitor doubles for every 10deg C temperature drop). At this time electrolyte will simply dry out causing increase in internal resistance (ESR). Endurance is defined as lifetime under extreme conditions (max voltage, max ripple current, max temp). The reason for this is self-heating caused by max ripple current thru increased ESR. Since ESR increases with temperature at certain point there would be thermal runaway. Capacitor has fuse (rubber plug or weakened top) to prevent huge explosion.
For this to happen capacitor has to be really bad (dried out) and you will hear it way before. It is also not likely that anybody would design anything operating even close to max ripple current allowed not to mention 105degC temperature.
In 50 years when it fails I will be already dead, so please don't try to contact me.
