Overall, I believe humanity should learn to take better care of Earth and really master our domain. Machine life would do amazing things with
There is that sentiment, of course. But machine life on Mars misses the overall issue. We need a stable, sustainable colony of humans somewhere away
from Earth--not robots: humans. When the next asteroid hits, we'd better be ready to move it out of our way or move ourselves out of its way.
Eventually, we have to be out of this solar system, too, but that is likely out of the question for our generation. Small steps, but we've got to make
I am NOT arguing from sentiment. We do not need an asteroid backup plan any more than we need any other backup plan for an unlikely event that is all
but impossible to prepare for currently. The smart move is rolling the dice on an extremely low-risk event for another one or two hundred years until
such a time as it is practical to invest in luxury backup systems for extremely low risk events.
Furthermore, what you want isn't even currently possible. Starting an unsustainable Mars colony now will offer no increased likelihood for survival
whatsoever as it will be dependent on Earth. In the mean time, we are far more likely to be destroyed in a wide variety of other ways that we need to
focus on for now.
Are you familiar with the concept of opportunity cost? Spending so much on an enormously expensive and yet feeble Mars colony would crowd out sensible
pursuits and real progress.
While I disagree vehemently that asteroid preparation should be a species wide priority, taking it seriously for a moment, I think that what you
really want is ocean habitation and deep underground habitation. Heck, we don't even have a sustainable population in Antarctica. If we can't do it on
Antarctica first, then why go all the way to Mars?
There is so much work to do on Earth first that would keep the human species alive through all the asteroid strikes which we can practically do
something about. Unlike a sustainable and independent Mars colony, many are near term achievable goals. Beyond the Earth, sustainable orbital habitat
would seem far more potentially useful than an extremely remote Martian colony.
I understand that whoever invented the wheel may have dreamed of traveling to other stars, but there are a lot of intermediate steps, most of which
can not be skipped, and some of which should not be skipped. What if the inventor of the wheel had instead only dreamed of traveling to other stars?
