>The decision to terraform Mars would also exhibit hubris.

Speaking of hubris: if we terraform Mars, people are going to want to climb Olympus Mons. Perhaps the volcano would acquire a reputation and body count similar to Everest.

Obviously the future holds great potential for lifesaving technology, but at the same time there's always purists. After all, the people who have climbed Everest probably wouldn't have if there wasn't any danger involved.

I imagine much of the danger would depend upon the finer details of how the Mars was terraformed. Namely sea level, atmospheric composition, and anything else that affects weather at altitude.

Would reaching the summit even be possible without oxygen? It wouldn't be on Earth at that height, but I've no idea if that holds for a terraformed atmosphere on another planet.
