capacitors are rated for 105 C temperatures, probably he dropped his jedi sword on them...
electrolytic capacitors come in a range a temperature ratings, commonly 80,105 and 130 C
capacitors are no more susceptible to failure during power up than any other component
I think the lesson here is don't make generalizations.
Capacitors of some types are very vulnerable to damage from surge currents ie solid tantalum and aluminum electrolytics. Power on events can, in poorly designed systems, result in large surge currents.
