  • If I was guessing, in general, I think people who advocate for a pure meritocracy in the USA feel the world should be evaluated in more black and white, objective terms. The financial impact and analytic nature of STEM and finance make it much easier to stratify practitioners “objectively” in comparison to finding, for instance, the “best” photographer. I think there is also a subset of US culture that thinks that STEM is the only “real” academic group of fields worth pursuing, and knowledge in liberal arts is pointless -> not contributing to society -> not a meaningful part of the meritocracy. But I’m no expert.


  • As a general rule, yes. People who are able to better perform a task should be preferentially allocated towards those tasks. That being said, I think this should be a guiding rule, not a law upon which a society is built.

    For one, there should be some accounting for personal preference. No one should be forced to do something by society just because they’re adept at something. I think there is also space within the acceptable performance level of a society for initiatives to relax a meritocracy to some degree to help account for/make up for socioeconomic influences and historical/ongoing systemic discrimination. Meritocracy’s also have to make sure they avoid the application of standardized evaluations at a young age completely determining an individual’s future career prospects. Lastly, and I think this is one of common meritocracy retorhic’s biggest flaws, a person’s intrinsic value and overall value to society is not determined by their contributions to STEM fields and finance, which is where I think a lot of people who advocate for a more meritocracy-based society stand.





  • I mean if the only way they’re gonna have jobs is through predatory hiring practices that could leave them fired and without severance, then yeah. Because if the company is planning on hiring these younger workers for the long-haul, then this shouldn’t be a significant change. I think overall national policy should discourage unnecessary high-turnover and predatory hiring. I’m sure there will be situations this is still unavoidable, but that doesn’t mean we have to endorse it by way of law/policy.


  • I’m going to digress from the economics a tad and focus on the ethics of this. I feel like companies should be on the hook for this. You should invest in capital (including human labor) based on your confidence in its expected return. Companies should not be able to hire a myriad of workers for funzies and not have to meaningfully consider if that person will be necessary in 6 months. If it is a legitimate business venture, then the cost of potential severance for new hires should be folded into the economics of the decision to pursue that venture. Larger severance pay/worker protections encourage employers to not utilize exploitative hiring practices.


  • It depends on the half life of the element in question. The most comparable concrete thing we can compare this to with real numbers because we know it works is an RTG. RTGs are solid-state generators, but people could colloquially refer to them as “batteries” and not be terribly wrong. They take a quantity of a radioactive material and allow it to decay, using the heat given off to establish a thermal gradient which is then converted to electricity via thermocouples. Most of these are “fueled” with Pu-238 (at least the ones for spacecraft), which has a half life of 87.7 years. That means in 87.7 years, if you started with 4kg of Pu when you built it, you’d have only 2kg of Plutonium left. If the Pu decayed only into stable isotopes (it doesn’t) then your radioactive emissions/decay would also be exactly halved at this time. If the electrical system is perfectly efficient this would also halve the electrical power produced.

    I provide this all as background because to answer your question you have to know three key factors about the device to determine the lifetime of the battery. The half-life of the isotope used, the minimum electrical requirements of the device you’re powering, and the amount of radioactive material in the initial battery. The battery’s lifetime is determined by when decay will decrease the ongoing energy output below the minimum current and voltage requirements needed by the battery. The longer the half life of the isotope, the slower this decrease is and the less initial overpowering that is required.

    Ex. If you use an isotope with a 12.5 year half life for a “50-year” battery, you would need to start with 8 times the material needed for your minimum power output requirements. If you use an isotope with a 200 year half life, you only need 19% more starting mass than you minimum requirement. The first battery will produce 8x the power at the very beginning, while the second will only produce 18% more.





  • A lot of the really prestigious medical schools/residency programs have a reputation for a toxic culture, and this means by and large they attract a larger share of toxic applicants. Their programs are really focused not on training great bedside clinicians, but on training people who will attempt to change fields through research and public policy. Unfortunately, the toxic nature of these programs, and their immense emphasis on publishable output and reputation, likely attract a larger fraction of narcissists with the skills necessary to mask their inappropriate behaviors when needed in comparison to other programs. That is not to say that all Harvard trained physicians are horrible people, I’m sure the vast majority of them are fantastic, but I would be money that Harvard attracts a greater fraction of the kookes than your average midtier medical school.



  • All remote based typing is awful, T9 included. I can’t speak for everyone, but I can type with swipe gestures on a virtual keyboard via remote faster than I can input T9 text. I’m unaware of any stock remote for a device with a full keyboard. I would argue Apple has text entry perfected at least as well as any other major manufacturer. You have virtual keyboard entry, solid voice-to-text, and it can be configured to push a notification to your iOS device when you enter a search bar which will auto-open to the remote app and pull up the keyboard. Because of this feature passwords can also be autofilled from Keychain to make logins easier.

    You may personally prefer T9, but I’ve never seen anyone in the last decade input anything into a TV via T9. And you’re asking why it doesn’t have voice input, when it does. You admit to having never used an Apple TV yourself. I hate the idea of app-only interfaces features, but this isn’t a case like that. Maybe you should understand the features of a product before you call it “fucking stupid”.
