Human self-sufficiency in space— what’s needed for any real redundancy-- is for sure >50 and probably >250 years away.

Gold is a worse conductor than copper. The benefit is just protection from corrosion.

(Copper conductivity is 6 * 10^7 S/m, gold is 4*10^7 S/m. Silver is 6.3 * 10^7, but very prone to corrosion).
