I love the vision. I am sure one day we will do this. Take a look at his recent hour-long presentation at the 67th International Astronautical Congress in Guadalajara, Mexico, where he outlined the long-term technical challenges that must be solved in order to support "the creation of a permanent, self-sustaining human presence on Mars."
And if you don't have an hour to spare but would like to get an idea of the vision, watch this simulation of his envisaged SpaceX Interplanetary Transport System.
It would be an incredible adventure. It would be the most inspiring thing that I could possibly imagine.
Life needs to be more than solving problems every day.
You need to wake up every day and be excited about the future, and be inspired, and want to live.
