alt Hacker News> Colonizing Mars is such a dumb idea.
A back-of-the-napkin calculation puts humanity's total military expenditure at about $100 trillion (USD adjusted to 2022 $) since 1949. That's not accounting for lives lost, infrastructure destroyed, and all the other negatives that come from war. Humanity is spending unfathomable fortunes just to be able to kill each other. And you're saying colonizing Mars is a dumb idea? Humanity is wasting its potential on the stupidest shit you can imagine. Colonizing Mars is a galaxy-brained idea compared to most of what we're spending our money on.
And of course colonizing Mars is trivial compared to terraforming Mars, which you can make a stronger argument against. "If you can't terraform Earth, then you can't terraform Mars." Of course that argument misses the point that if you set terraforming Mars as a goal of humanity, then we focus our efforts on developing the technologies that would allow us to terraform Earth as well (long beforehand, I might add). Focusing humanity on a course to accomplish an immense feat of engineering always produces an immense amount of positive externalities.
You could have levied the same argument against the Apollo program, any of FDR's New Deal megaprojects, the national highway system, the Large Hadron Collider, ITER, etc. And of course people do say we shouldn't be "wasting" our money on such things. I say: how about we keep doing all those projects and more, and stop wasting the vast majority of our money on stupid shit like bombs that in the best case sit in a warehouse until they decompose into duds, and in the worst case kill some wedding attendees and set humanity back.

All of those had (and always had) far more obvious benefits than colonizing Mars, including the squishy benefit of "beating the Soviet Union to a contested goal."
You can disprove me by stating plainly what the benefits of colonizing Mars would be?
Mars is extremely terrible. I don't understand why we'd want to colonize it, versus any number of other things we could do with that immense effort. Visit it, sure, I guess, maybe, but colonize? LOL why?
Yes, we waste a ton of money on military. Historically (middle ages) it’s been even higher as a percentage of GDP. A higher peace dividend would probably be good.
But not all military spending was wasteful. The military and military adjacent orgs have invested in tons of useful R&D with civilian applications.
The fact that we do dumb things does not make the specific plan of colonizing Mars a good idea. Hell, we could try to colonize the asteroid belt, at least that doesn’t involve dropping down some enormous gravity well to visit a dead planet.

I’m not sure what “the argument” is here, I didn’t really present much of an argument (I think colonizing Mars is self-evidently dumb). But if the argument that is being levied against these things is that they are all too expensive—I disagree that it applies to some of the things in your list. The New Deal and the Highway system had positive effects for existing people. Maybe the Apollo program was frivolous on some level, but at least it had a plausible goal.
We have a finite budget, I agree that it would be better to spend less of it killing each other, but it will still be finite. We should try to do something more useful than Mars.
