alt Hacker NewsThe proposal tries to go against the current trend of US isolationism which burned a lot of good will with the rest of the world, and gain a bit of soft power back. Noble goal, but I’m not sure who wants to align behind the US today and risk getting dumped tomorrow.
On the topic of mirror life, doesn’t it need mirror food? I was under the impression that they couldn’t consume natural sugars for example, and so on. They’re talking about mirror life that uses non-mirrored molecules to propagate? How is mirror life building itself without mirror-everything-else?

The raw materials for photosynthesis and nitrogen fixation (water, carbon dioxide, and nitrate) are achiral. Maybe mirror lives can start from scratch like our ancestors.
One could design a mirror life form that uses mirrored amino-acids to build its proteins and also mirrored carbohydrates as building components, but which would nonetheless also have enzymes for the hydrolysis of normal proteins and carbohydrates and for their oxidation in order to produce energy, so it could eat non-mirrored food as a source of energy, even if it would need to synthesize for its growth mirrored molecules.
Mirrored amino-acids and carbohydrates are not completely missing in nature, some of them are produced by certain living beings for various purposes, but they are not used for building proteins or other macromolecules, i.e. they are not usable for growth.
