  • It wasn’t originally my claim - I replied to your comment as I was scrolling past because it had a pair of sentences that seemed dodgy, so I clicked the link it cited as a source, and replied when the link didn’t support the claim.

    Specifically, I’m referring to

    A single bit flipped by a gamma ray will not cause any sort of issue in any modern computer. I cannot overstate how often this and other memory errors happen.

    This just isn’t correct:

    • loads of modern computers don’t use DDR5 or ECC variants of older generations at all, so don’t have any error-correcting memory. If the wrong bit flips, they just crash.
    • loads of modern computers don’t exclusively use DDR5, e.g. graphics memory (which didn’t have error correction until GDDR7 but can still cause serious problems, e.g. if a bit flips in a command buffer and makes the GPU write back to the wrong address in main memory, overwriting something important), and various caches (SRAM is vulnerable to bit flips from various kinds of radiation, too). If the wrong bit flips, they just crash.
    • Compared to other computer problems that can put the wrong data into memory, like experiencing a bug because a programmer made a mistake, or even just a part wearing out from age, memory errors are really rare, so anything implying normal people need to care is thoroughly overstating their prevalence.

  • That study doesn’t seem to support the point you’re trying to use it to support. First it’s talking about machines with error correcting RAM, which most consumer devices don’t have. The whole point of error correcting RAM is that it tolerates a single bit flip in a memory cell and can detect a second one and, e.g. trigger a shutdown rather than the computer just doing what the now-incorrect value tells it to (which might be crashing, might be emitting an incorrect result, or might be something benign). Consumer devices don’t have this protection (until DDR5, which can fix a single bit flip, but won’t detect a second, so it can still trigger misbehaviour). Also, the data in the tables gives figures around 10% for the chance of an individual device experiencing an unrecoverable error per year, which isn’t really that often, especially given that most software is buggy enough that you’d be lucky to use it for a year with only a 10% chance of it doing something wrong.



  • Some of the charity is self-serving, e.g. eradicating diseases means he’s less likely to catch them (and really any billionaire not funnelling funds to pandemic prevention etc. is being moronic), and founding charter schools on land he owns so over the life of the school they pay more in rent for the lease than they cost to build is just a tax dodge. Most billionaires are just so evil that they won’t spend money on themselves if other people who aren’t paying also benefit, so in comparison, Gates’ better ability to judge what’s in his interests makes him look good.



  • You should be leaving enough stopping distance between yourself and the next car that someone can merge easily and you have time to react by slowing down or moving to the next lane to make space for them. If you don’t have that much stopping distance, then you’re already in danger if the car in front brakes suddenly, e.g. if they need to do an emergency stop because of something you’ve not seen, they have a medical event making them lose consciousness and accidentally step on the brake pedal, or their car breaks down in a way that forces the breaks on.


  • In a lot of the world they’re regulated as novelty items, so free from the regulation that stops harmful chemicals being in things like kitchen utensils and childrens’ toys, despite many of the same potential risks being present. You don’t need to use a corner-cutting regulation-ignoring retailer like Wish to get your fix of toxic plasticisers etc…




  • They focus on the low end, but a lot of people who only want low end GPUs care about Minecraft, and their OpenGL performance is abysmal, so Minecraft runs like molasses. If you play a lot of Minecraft, Nvidia’s cards manage to be much better value. There’s no reason why this couldn’t be fixed if they’re willing to invest in writing native OpenGL drivers instead of going through a compatibility player or mitigated if they invested more in making the compatibility layer faster, but that would mean deciding they’re losing a lot of sales this way, as it wouldn’t be cheap.







  • Investors have been happy to incentivise companies to hire idiot CEOs and managers who say the right buzzwords but reduce output by making bad decisions and only hiring people who don’t think they’re bad decisions, so an automated buzzword-dispensing idiot isn’t necessarily going to seem to investors like a downgrade compared to what they think most workers are. They’re just as likely to think AI lets them invest in companies where even the lowest tier employees are potential CEO material, and continue not noticing that the per-employee efficiency keeps going down. Data showing that layoffs nearly never pay for themselves doesn’t stop stock prices soaring whenever one happens, so I wouldn’t expect data showing AI makes companies less profitable to stop stock prices going up when a company announces a new dumb way they’ll use it.





  • If you trust Adam Smith, an efficient market would quickly make new goods and services available for the lowest possible price. People are supposed to be incentivised to sell things, and competition is supposed to stop an excessive amount of money being diverted to profits instead of reinvestment and price cuts. There are supposed to be systems in place that ensure that there are always opportunities for competition, but the wealthiest have the most power to erode those mechanisms and the most interest in eroding them, and neoliberals think an Ayn Rand novel is the definitive text on how capitalism works rather than Adam Smith’s work, so even if you land in the capitalism makes everyone better off mode, it doesn’t last for long before it falls back into fuedalism with extra steps mode.
