* Acid atmosphere is mostly near below the surface, and is fixable in the long run.<p>* Suface access can be done by robots, resource extraction can happen on the surface and balloons can lift the resources to the habitable zone.<p>* No magnetic field, agreed. Problem.<p>* Larger delta-V, less of an issue in the long run. It&#x27;s easier to get to Detroit than Cuba from Toronto, but most people winter in Havana.<p>* Launch systems are easier that bioengineering.<p>* Water can be imported or synthesized. We&#x27;ll have lots of extra O2 with all that CO2 we&#x27;ll be converting.<p>* We haven&#x27;t really looked at Venus. We&#x27;ve sent some soviet probes in for a couple of hours each back in the 80s, and they focused on the hellish surface.<p>In terms of long term development of human cities, I still think Venus is a far better candidate than Mars, even if Mars is easier for now.
