<p>Neither EVs nor ICE cars spontaneously combust unless there's a design flaw. Even when this happens it tends to be very rare, but the Chevy Bolt fires for example were fixed with a recall. Similarly a Ford recall last year fixed a problem where fuel injectors could leak and cause an engine fire.<p>EVs and ICE cars can both catch on fire in a bad enough accident, but this is true regardless of the age of the vehicle, and tends to be more sudden and violent with gasoline explosions vs battery fires.</p>

<p>I think this is a dangerously half-true way of thinking.<p>Yes, there are times when hard work feels great, and it's absolutely worth seeking out this kind of work.<p>But any serious endeavor is going to have times that are a slog, and your ability to stick with it through the bad times will very directly dictate your ability to get back to the good times.</p>

<p><i>SWE salaries are a massive cost. Improving productivity is one way of offsetting that cost.</i><p>In a lot of businesses you get praise and look important if you’re responsible for leading a large group of highly paid employees, more so then if you have a smaller team.<p>Thus the motivation is frequently to spend as much money as possible, not to improve efficiency.<p>If you improve efficiency then maybe you just get your team size cut and people ask hard questions about why you needed all those resources in the first place.</p>

<p>The trouble is that making progress in leaps is often mutually exclusive with being productive in the short term. It’s hard to think big and plan long-term when you’re constantly overwhelmed with what’s in front of you.<p>Slow Productivity by Cal Newport talks about this trade-off extensively and provides interesting points of reference where real famous historical figures achieved incredible things in ways that would seem slow and lazy by modern standards.</p>

<p>Truly great art, the kind that expands the field of artistry and makes people think, requires creativity; if you make something that's just a rehashing of existing art, that's not truly creative, it's boring and derivative.<p>This has nothing to do with whether a human or AI created the art, and I don't think it's controversial to say that AI-generated art is derivative; the models are literally trained to mimic existing artwork.</p>

<p>I disagree that the current generation of AI has "solved" artistic fields any more than it's solved math or programming.<p>Just as an LLM may be good at spitting out code that looks plausible but fails to work, diffusion models are good at spitting out art that looks shiny but is lacking in any real creativity or artistic expression.</p>

<p>I think you might be missing the point of the article: the study being cited isn't trying to establish the existence of a "language brain" or a "math brain", that's just the way the headline editorialized it to help people understand the conclusions.<p>The conclusion of the study was that linguistic aptitude seemed to be more correlated with programming aptitude than mathematical aptitude, which seems fairly interesting, and also fairly unconcerned with which specific physical regions in the brain might happen to be involved.</p>

<p>I will never buy another Tesla again for political reasons, but regarding reliability: their new models have <i>always</i> had reliability problems, but then reliability has always gotten much better within a year or so.<p>I don't know if the Cybertruck will follow the same pattern, or if the whole company has jumped the shark, but if we're looking for non-political opinions I would not necessarily write them off on quality issues alone.</p>

<p>I agree the whole thing was shady, but did they really never care about solar? I thought the solar roof was announced well after the SolarCity deal, and it seemed like they were serious about ramping that up for a while (though obviously that never really went anywhere or fulfilled any of the original promises either).</p>

<p>The article is flat out wrong. The reason purple and violet look similar is not a trick of the brain, and has nothing to do with the color wheel "wrapping around"; it's a natural result of the frequency response curves of the three types of cones in our eyes. The two colors stimulate our cones in the same way, so of course they naturally look similar.<p>Most diagrams of our cone frequency responses are subtly wrong. Diagrams typically show three separate smooth, overlapping peaks, centered around red, green, and blue. What they leave out is that our L-cones (the "red" cones) also have a separate little sensitivity bump way off in the violet end of the spectrum. So when you see violet light, it's actually stimulating both the cones that are most sensitive to red light and the ones that are sensitive to blue light. This is pretty much the same stimulation pattern you get if you send both pure red and blue light into your eyes together, which is why purple and violet look so similar.<p>If you Google "cone sensitivity diagram" you'll mostly find the misleading versions of the diagrams, but you can see one that includes the extra bit of high-frequency L-cone sensitivity in this paper, for example: <a href="https://hal.science/hal-01565649/file/Vienot_ConeFundamentalsModelFutureColorimetry_LRT2016%20(1).pdf" rel="nofollow">https://hal.science/hal-01565649/file/Vienot_ConeFundamental...</a></p>

<p>Yeah, this is a limitation, but generally if you have hard constraints like that to maintain, then yeah you probably should be using some sort of centralized transactional system to avoid e.g. booking the same hotel room to multiple people in the first place. Even with perfect conflict resolution, you don't want to tell someone their booking is confirmed and then later have to say "oh, sorry, never mind, somebody else booked that room and we just didn't check to verify that at the time."<p>But this isn't a problem specific to CRDTs, it's a limitation with any database that favors availability over consistency. And there are use cases that don't require these kinds of constraints where these limitations are more manageable.</p>

<p><i>What I find hard to imagine is how the app should respond when synchronisation fails after locally committing a bunch of transactions... Manual merging may be the only safe option in many cases.</i><p>Yeah, exactly right. This is why CRDTs are popular: they give you well-defined semantics for automatic conflict resolution, and save you from having to implement all that stuff from scratch yourself.<p>The author writes that CRDTs "don’t generalize to arbitrary data." This is true, and <i>sometimes</i> it may be easier to your own custom app-specific conflict resolution logic than massaging your data to fit within preexisting CRDTs, but doing that is <i>extremely</i> tricky to get right.<p>It seems like the implied tradeoff being made by Graft is "you can just keep using the same data formats you're already using, and everything just works!" But the real tradeoff is that you're going to have to write a lot of tricky, error-prone conflict resolution logic. There's no such thing as a free lunch, unfortunately.</p>

<p>Placebo is an expectancy effect. I don't know all the details of OP's story, but there are all kinds of plausible reasons I can imagine that someone might have different expectations for one drug over another.<p>It might not even have anything to do with the drug itself: mental health issues tend to wax and wane on their own over time, so if someone happens to feel better right after starting a new medication, it's easy to think "oh hey this one must be working" and then that can trigger the placebo effect and turn into a positive feedback cycle.</p>

<p>Keep in mind that studies find a strong effect for placebos: the numbers are not saying "these pills do nothing" they're saying "these pills seem to do a lot, but placebos do almost as much".<p>Obviously the effect feels extremely real to you, but we wouldn't see a strong placebo effect in the numbers if people on placebos didn't <i>genuinely feel much better</i>.<p>I get that it feels like the second drug worked much better, but expectancy effects and internal narratives are extremely strong, and they're impossible to untangle at the level of an individual.</p>

<p>Exactly this.<p>Many double blind studies are completely broken due to side effects triggering a stronger placebo response, and this is an especially huge problem for drugs like SSRIs where a placebo gets you about 80% of the benefit of the actual drug.<p>Similar to the study you linked, there was a more recent study where they found that for the SSRI escitalopram (aka Lexapro), the benefits disappear when you lie and tell people that they're receiving an active placebo that mimics the side effects of an SSRI. That is, if people don't actually think they're taking an SSRI, they don't get any benefit.<p><a href="https://app.dimensions.ai/details/publication/pub.1142338190" rel="nofollow">https://app.dimensions.ai/details/publication/pub.1142338190</a></p>
