"Due to ESR, all electrolytic capacitors heat up a bit, leading to drying out of electrolyte and eventual failure."

Well, if the ESR was so high such that the capacitor would heat up as a result, then it wouldn't be a very good capacitor, now, would it?

Or, from a different angle, in order to get enough current through that ESR such that heating actually takes place, you'd very likely exceed (by a wide margin) the capacitor's working voltage.

Yes, heating does shorten the life of a capacitor, but the primary mechanism of that heating is NOT ESR.
