I agree that the obsession with Mars is exaggerated is not the best planet for living, it would be wise to address the development of the engines, or technology-terraforming (at least in limited areas), such as the impact craters, not the whole planet.

For example the Chinese are very wise to approach this question, they want to first develop the production of helium-3 on the Moon, this element is ideal for creating fusion energy sources, it can help to make a breakthrough in the energy sector, and create new technology.
