  • A futurist is someone who has an interest in or studies the possible futures of our world, and who generates work related to their predictions of the same. It’s a pretty broad term, and would encompass certain academics, as well as writers and other enthusiasts. Their basis in evidentiary processes is obviously going to vary greatly, by it’s not necessarily accurate to say that they are simply guessing. It’s not a licensed term, but neither is “author” or “crypto-bro” or “politico” and yet one can certainly be any of those without any credentials.

    There are certainly some elements of guesswork and hypothesis in any predictive field. Certainly there will be authors out there who might style themselves as futurists, but whose works are much closer to fantasy than speculative science fiction. I (personally) think it would be grossly inaccurate to call Star Wars a futurist work, for example. But I think one can easily look at the history of technological and social developments and create something that is a reasonable prediction of the future. I think Weir does a respectable job of portraying a mostly-plausible scenario in The Martian, by comparison. Asimov’s work has various examples that could probably be called Futurist, as well.

    Why might a director or script writer consult with such individuals? Well, partially I suspect it’s to claim that they did. It’s a headline and marketing thing, of course. But also, because they’re making a piece of media that’s not necessarily in an area that they’re intimately familiar with. Even if you’ve made several science fiction movies before, I think it’s probably obvious that taking advice from someone who has spent thousands of hours considering the minor nuances and smaller details of something would have some useful insights.







  • Something other posters have overlooked here is that one life is guaranteed to be saved if you pull the lever. There are 5 tracks in the image, but the ratios use quarters. If you pull the lever, you have saved one life. You have a 75% chance that you have saved one life with no consequences. You have a 25% chance of killing a net of 4 people. By that method, your expected number of kills is 1, no matter your choice.

    However, I really think I look at it more on the chance of good outcomes, personally. If I pull the lever I have a 75% chance of saving everyone, and only a 25% chance of bad outcomes. I can live with that choice. I can live with the decision to take action, because to not take action is still choice.



  • A lot of these calculations solve this by using a lower expected growth rate, to offset the expected inflation. It lets you have the more simple conversations in today’s currency values, which are easier to reason about.

    That’s not the case in this particular example, and you’ve correctly identified a deficiency. I raise the point for the benefit of any curious readers who look into other conversations on the topic.






  • I hate when these sorts of statistics point to “the top 10%” as the problem based on numbers like this. It’s simply much less broad than that. Of all wealth, the top 0.1% holds 14.5%. The next 0.9% holds 17.3%. The bottom 50% hold only 2.5%. The top 1% of households hold 12.72x as much wealth as the bottom 50%. And, notably, the bottom 10% of households have less than $1000 in net worth. The bottom 8% of people have $0 or less.

    A household which is at the 90th percentile for Net Worth has a net worth of roughly $2,000,000, including equity in their home. You get to the 95th percentile before you double that to $4M. The 90th percentile has 1000x higher net worth than someone with $2,000 to their name, which seems obscenely unfair when described in that way. However, a net worth of $2,000,000 would provide a retiree a mostly-safe withdrawal rate (4% or $80,000) of around the median income of ~$84,000. (This doesn’t actually check out since it includes equity in the home, but as a simplification.) Retirees have access to social security and tax-advantaged accounts and the like, but someone who ends up with a net worth of $2M could live only a median lifestyle without working.

    Is a net worth of $2,000,000 a very large number and a large chunk of wealth? Of course it is. But it’s not like, obscene wealth. If I gave a random American $2M it would change their lives profoundly, but the people who have a net worth of $2M aren’t the ones who are ruining our lives. They’re just not.

    The top 0.1% hold 14.5% of the wealth. The top 1% hold 31.8%. The bottom 10% hold less than 0%. That’s the ball game.

    Disclaimer: I have not rigorously cited my sources, nor verified all my figuring. However, most of this is pulled from the Fed data linked in the article. Other stuff is pulled from sources which cite the same, though I’ve not run a rigorous analysis of the maths. My work should not be cited as correct, it is intended to be illustrative. That said, I’ll happily remedy any errors that others might notice!




  • Pretty much. Leave sharing policies are usually set up such that in some sort of extraordinary medical circumstance, employees can transfer paid leave to one another.

    The idea is sorta that if a loved one has a major medical emergency and needs a lot of care for 3 months, other employees can transfer paid leave to help cover gaps. This makes sense as a way to cover edge cases in extreme circumstances, but “is having a child” definitely isn’t such a case.
