> If you want to get depressed about all the problems with trying to colonize Mars
I had the opposite reaction. I thought it set forward a realistic set of challenges we have to solve and experiments we have to do before building anything more than a research outpost on Mars. That, in turn, makes a permanent Moon base more valuable.
Standout problems were low- and zero-g trauma medicine, plumbing (something Artemis II started working on) and mammalian reproduction.
This is on my reading list. I've read synopses of it, and I don't think it's going to change my mind a lot. I'm still long-term pro-space-exploration, but even before this book I'd come to the conclusion that this is a lot harder than naive nerds tend to think. I think it's worth doing and probably will be done eventually, but it's gonna take a while.
I've had the thought for some time now that the most viable path to settlement in space -- if humans actually decide they want to do it -- is to settle space. Not the Moon, or Mars, or Venus, or anything else, but space itself.
In space you can build big rings and spin them for 1g gravity. We don't know if 1/6 or 1/3 gravity is enough for us to reproduce and prosper, but we know 1g is. Your environment is hermetically sealed and you control what comes in and out. You could, once you get good at this, actually create hyper-habitable environments tuned to be ideal for human life. People aren't tracking in nasty asbestos-like regolith or perchlorates or anything else you don't want.
Most reasonable near-mid term proposals for living on Mars or the Moon I've read about call for spending most time underground. Going there to do that seems pointless. Living in space itself could be much nicer.
The interior of such a ring would look nothing like this very Hollywood "luxury hotel" thing, but this little short film gives you a sense of what the relationship to the external space environment might be like:
Radiation is still an issue, but there's ideas for that that could work for a ring in hard space vacuum that don't work as well on a planet. One is to put a big superconductor around the ring and give it a magnetosphere. The whole habitat is a big electromagnet. Most cosmic rays and solar particles are charged. The power requirements are not as great as you'd think.
For resources asteroids are probably better than planets. The solar system is full of asteroids that appear, from what we've seen, to be incredibly rich in raw materials, and these bodies have such low gravity that you could literally pull up next to them and go dig stuff out of them. The delta-V requirements of sending stuff back to your space-city are literally at the scale of "throw it real hard." Their low mass also means you don't have to dig deep and the heavy elements didn't sink to the core. You're going to find gigantic amounts of stuff like gold, platinum, pure iridium, fissile materials, etc.
Free living space habitats could move around. There could be moving towns and cities, more or less, that could tour the solar system and pick up resources and rendezvous with each other. Think steampunk style traction cities in space, kind of.
Politically you leave behind at least some of terrestrial politics. I'm not naive enough to think people would never find anything to fight about. We're good at coming up with stuff to fight about. But the notion of battling over land pretty much goes away. Space is called space for a reason. Culture wars become less relevant if everyone's town is mobile and if you don't like your neighbors you just move your whole "pod" around. Resources seem very abundant. I don't see a ton of resource competition unless we discover some critical or massively valuable resources that genuinely are rare and available in only a few places.
In the very long term, this path leads to the evolution of an actual spacefaring civilization rather than simply a repeat of terrestrial politics on another planet. Generation ships to the stars would be a natural evolution of this. After doing this for a few hundred or a few thousand years, we'd get so good at it that the idea of a caravan of these mobile cities departing for Centauri or Tau Ceti becomes imaginable and not a total suicide mission.
Compared to this I think going to Mars is a dead end. Even if we go there and survive and prosper, now we're just doing planetary civilization again. We're back to squabbling over dirt. The real evolutionary leap is doing something different. Fish didn't come on land to stay fish.
But there's also an argument that there's no point in trying until we at least have a couple of key technologies: fusion, very good automated manufacturing, and very good robotics. Fusion is key for enabling scalable power and mobility. Automated manufacturing and very good robotics are probably key to self-sufficiency.
Trying to do the "real space age" before the key technologies exist might be akin to, say, trying to start the EV revolution with lead-acid batteries or the PC revolution with vacuum tubes. While it's technically possible to try, it's just not going to "take."
It's not that they made more money from merchandise, it's that they sold more t-shirts than albums. Implying that more people were interested in the "image" of punk rock than the music.
I guess that's the definition of 'iconic' - many a time I have approached someone wearing a Ramones or Motörhead T-shirt trying to chat a bit, only to be told 'Sorry, don't know the music at all, but the shirt is cool...'
Although the article is unsure whether they sold more t-shirts than tickets, implying that people were interested in the music in a live capacity.
Which is a reasonable implication given that punk grew up around the DIY culture. A commercially produced recording doesn't exactly align with the interests of that type of community, even where that community enjoys the music itself.
It's the incentives and everything is a trade off. Time to market, performance, features: none of these choices are made in a vacuum. Oh, and people like to go home and see their families once in a while.
As a developer of over 35 years, I feel like I hear the same arguments over and over again. "Programmers used to care about performance!" No they didn't, they just had no choice because computers sucked and you had to work on performance or your application would barely run. "Progammers used to care about the quality of their code!" Really. You apparently never worked on legacy systems with years of hacks and spaghetti code that took an afternoon to trace through just to figure out what it was doing.
People haven't changed. Kids aren't lazier these days. The incentives are always just to ship as fast as possible. Performance will be dealt with when and if it is so bad that the customer complains and not a moment sooner.
When I was much younger I fancied myself a "craftsman" of software. But any "craft" I was able to bestow on my software was in spite of the surrounding incentives not because of them. Software is closer to assembly line work than craftsmanship and LLMs are just driving that point home faster and harder than ever.
I still love software development after all these years but it's entirely because I love solving problems and computers still fascinate me the same as they did when I got my first TRS-80 Color Computer at age seven. Nobody that's not a programmer cares as long as the software does what they need it to and does fast enough that they don't start wonder why they have to use this piece of crap software in the first place.
Correct. More to the point, when it appeared many on the left attempted to wave this away by claiming that it was, as one put it, a "gentle satire" <https://en.wikipedia.org/wiki/Animal_Farm#Reception> when anyone who has read Animal Farm knows that it is in no way gentle in its satire.
What nl is attempting to do above is the latest iteration of what Animal Farm and 1984 both received from those who could not stand the spotlight of their scrutiny: Claim that the target is something else, and/or that Orwell's attacks are so pedestrianly obvious (since "everyone knows" that Stalinism is bad) as to be pointless.
I'm a strong supporter of the "I did it because I wanted to see if I could do it" ethos. So this isn't a criticism of the project itself, but I'm pretty sure a snap gun will beat this almost every time.
