But if an AI engineered a species of mirror life to have the chemical pathways needed to eat chemicals of the opposite sort then mirror life could digest regular life but regular life couldn't digest mirror life.* > *> The number of E. coli in a human gut is not regulated primarily by the > immune system, but by competition with other bacteria.* > *But there would be no bacteria in the gut except for mirror life bacteria. * * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* mlg > *And we know from experiments that Escherichia coli can grow very quickly > in an environment that only contains molecules that look the same in a > mirror, that is to say in an environment without chiral nutrients, if there > is nothing like an immune system to keep the numbers down.* > > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
