Agreed. For people to survive on Mars, earthlings would have to build the sealed cities there using drone technology, then trial them out by first populating them with animals controlled with that same technology. Earthlings would need the experience learnt by doing it on the Moon first, with its more workable one-second response time to drone commands. The sealed cities would be built like new Chinese cities today, the drone operators having learnt their skills on actual huge building sites like Luozhangmen. If there's nuclear devastation in the Mideast or annihilation by disease in Africa in the near future, such remote drone operation skills will likely be learnt by many competing players in those places. The encryption technology used in the droning must be unbreakable, so players must design and manufacture their own chips. And the people who do inhabit such cities on the Moon and Mars will probably have been specially bred in a country not subject to the restrictive laws governing biological innovation prevalent nowadays in the U.S. and Europe.
