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

    Space settlements are going to need support from Earth for the conceivable future.

    Even a destroyed planet from global warming or the middle of the ocean is infinitely more hospitable than the space environment.

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

    (Copper conductivity is 6 * 107 S/m, gold is 4*107 S/m. Silver is 6.3 * 10^7, but very prone to corrosion).
