I suspect that we're simply going to do the math and conclude "Humans can survive on Mars for 5-10 years before the radiation gets them, and we can send up new workers every 2-3 years, so as long as the rockets keep firing everything will be fine". And then the mass graves of Mars will form the foundation of every building on the planet within a generation.
