  • So, the major issue with settling moon is resource availability: water (!), carbon, fertile soil, and energy.

    On the moon you have none of that. Maybe, with a lot of luck, you find water somewhere. Then you need carbon, energy during the long moon nights, and soil that isn’t razor sharp particles.

    On Mars, you have all of them: low concentrations of water in the atmosphere, carbon from carbon dioxide in the atmosphere, soil that isn’t razor sharp (thanks to erosion), and the nights are short enough that you can make it through them.


  • Yeah I’ve been thinking about condensing the water out of the air, too. Problem is: how do you do that? If you use chemical dessication agents, then it’s effectively the same as if you let the soil absorb the water from the atmosphere. Just that the soil is already there and you don’t need to artificially manufacture dessicants. So it’s a bit simpler.



  • thanks, the link is interesting.

    The value proposition would be that it is important to understand the exact radiation pattern/schemes if we ever want to routinize spaceflight. In other words: effective solutions (to the problem of radiation) requires detailed knowledge of what the problem actually is, in other words, what kind of radiation are we talking about.







  • The technological innovations of the last fifteen years, from advertising enshittifcation to AI cheating, have largely been a disaster. We are sadly at the point where, as Ted Gioia says, “most so-called innovations are now anti-progress by any honest definition.” I dare say that if we could revert all digital technology to where it was in 2009 – before the invention of the retweet – we’d all be better off.

    I’d go back even further (to 2007) before the invention of the iPhone. The smartphone has, arguably, IMO been a bad, or at least premature invention. It created a generation of kids obsessed with their photographies, giving girls eating disorders and creating/spreading unrealistic beauty ideals, etc… Also it has severely disrupted teenagers’ social living, created sleeping disorders, chronic doomscrolling, addiction, and more bad stuff. The iPhone was, IMO, not ready for this world.


  • Depression has many causes:

    • For once, people work too much. It exhausts the body and we feel tired.
    • For two, there’s the meaninglessness of life. It’s difficult to stay motivated when nothing makes sense/there is no future.
    • Thirdly, positive sexual experiences strongly cure depression. Since the dating market is largely fucked (no pun intended), well that option doesn’t exist to large parts of the population.
    • Fourtly we’re socialized to hide depression. As everybody knows, the first step to solve a problem is to recognize it exists. Stigmatization of depression has held back effective treatment for way too long.
