Footprints on Mars (or another planet or moon) by 2040? Plausible, and likely by Space X or another like organization.
To add fuel to the greater debate here... Given enough time and regarfless of how you believe we will get there we will either evolve to the point where we no longer need a planet or we will drive to extinction through a planet catastrophy or our own stupidity. For the short term (Billion years or so) the likelyhood of a planet buster meteor, the "mother" of all viruses a series of "super" volcanos etc... is pretty real. At some point yes, the sun will expand and all life on this rock will end. Even if we are able to leave the planet and spread throughout the solar system, galaxy or even universe, again some day the end for all of those mentioned and us as a race is a given.
The Doomsday clock is still set at 23:58:00 or there about and humanity is still in its infancy. The odds are against us. But im an eternal optimist and betting against the odds. I would like to stick around for a bit and see what happens. [emoji41]
