Irrespective of the Tag Tantalum capacitor's rated VW (working voltage), they can become dangerous Roman Candles with age launching a red hot fireball.
Old capacitors of many varieties fail with age.
Watch this incident.
Some old electrolytic capacitors can be reformed.
Capacitors can fail on both sides of the voltage regulators.
Modern low ESR and low impedance ceramic and electrolytic capacitors can be used as replacements.
Whether they suffer the same issues in 20-40 years time has yet to be determined.
Did you know that with the correct PCB design most bypass/decoupling capacitors can be removed?
The first XBOX 360 prototypes were designed with no bypass/decoupling capacitors & worked perfectly well.
Bypass/decoupling capacitors were added as decoration & serve no functional purpose to placate those who didn't understand Power Distribution Network design.
Here's another!
