<p>The 0.1% thing ... Is that even the right label? I'm guessing one in a thousand people globally isn't using these mechanisms. The article spends some paragraphs on the world's richest person and his company's tax strategy. Is the millionaire next door quietly doing these things or is this about billionaires in which case it's more like one in a million.</p>

<p>ok so it seems pretty bad that they changed the index rules both to allow spacex in early and the wonky weighting stuff.
But if one already has index-based things that are likely to be captive on the wrong side of this, and one wanted to benefit or at least balance out, to confirm my limited understanding the goal would be:<p>- buy shortly after the IPO, ideally less than 15 days<p>- and sell less than 6 months later when lockups would end and insiders are set to cash out?</p>

<p>I think the "Leave them Behind" section at the end sort of ignores the whole "they will ruthlessly copy your material, and put aggressive extra load on your server while repeatedly stealing your work" dimension.<p>You can try to avoid consuming AI-generated material, but of course part-way through a lot of things you may wonder whether it is partly AI-generated, and we don't yet have a credible "human-authored" stamp. But you can't really keep them from using your work to make cheap copies of you, or at least reducing your audience by including information or insights from your work in the chat sessions of people who otherwise might have read your work.</p>

<p>> Microsoft bought it for OpenAI only, to train Copilot on the vast amount of code.<p>I think this gets the timeline wrong.

<p>While I agree that we keep reinventing stuff, in CS doesn't the ease of creating isomorphisms between different ways of doing things mean that canonicalization will always be a matter of some community choosing their favorite form, perhaps based on aesthetic or cultural reasons, rather than anything "universal and eternal"?</p>

<p>I worked for a startup that used clojure and found it so frustrating because, following the idiomatic style, pathways passed maps around, added keys to maps, etc. For any definition which received some such map, you had to read the whole pathway to understand what was expected to be in it (and therefore how you could call it, modify it, etc).<p>I think the thing is that yes, `[a] -> [a]` tells you relatively little about the particular relationship between lists that the function achieves, but in other languages such a signature tells you _everything_ about:<p>- what you need to call invoke it<p>- what the implementation can assume about its argument<p>i.e. how to use or change the function is much clearer</p>

<p>Do publishers really have fact-checkers? My understanding was that support for authors is now relatively minimal, even for established authors, and no one really has the time or resources to second-guess everything an author has claimed. I take as a key example Naomi Wolf learning after her book was "done" that a significant chunk of it was based on a misunderstanding of an admittedly confusing 19th century British legal phrase. 
<a href="https://nymag.com/intelligencer/2019/05/naomi-wolfs-book-corrected-by-host-in-bbc-interview.html" rel="nofollow">https://nymag.com/intelligencer/2019/05/naomi-wolfs-book-cor...</a><p>I think maybe the idea that a single author spending months or years on their research, which the publish as a single bound and polished work is misguided -- an academic trying to do similar work in multiple articles would have gotten review from peers on each article, and hopefully have not spent so much time working under a correctable misunderstanding.</p>

<p>This paper describes finding security related concepts and using them to steer at generation time. While this is an interesting contribution on its own, the approach could also be applied to a range of other concerns -- e.g. can we use this to steer away from performance problems? can we make llm code generation anticipate maintainability or readability issues?</p>

<p>If people want to try untested peptides, I think society should use that as the engine to _test those peptides_. Instead of buying something that's supposed to but may not be the peptide you want, you should pay 50+k% + data and get something that has a 50% chance of being the peptide and 50% chance of being a placebo, and you're _required_ to submit a report about effects and side effects before you can get a refill.<p>Rather than complain about how these things have not yet gone through real experiments and are marketed as having been "studied" rather than "effective", I would love to see society use the obvious demand for some of these to actually test them.</p>

<p>I get that the norms lean conservative and that's a good thing. But if someone says you should do a recall and the actual lab tests saying whether your product actually has toxin-producing bacteria haven't finished running yet, I can understand the desire to wait until the evidence is in.</p>

<p>I think some of it was just a belief that work you can see being done by a floor of people talking with their mouths and looking at screens in the same room is more real than the slightly less visible conversations in slack while looking at screens in their own rooms.<p>Open plan offices continue to be designed more for seeing the work happen than for doing the work. I spend a lot of mental energy on ignoring the distractions around me. No job has ever offered me a private office with a door that closes in exchange for being in the office 5 days a week.</p>

<p>> Meanwhile, you're a week behind on that Jira ticket for issuing JSON Web Tokens because there's no actively maintained JWT libraries for Gooby.<p>> I've seen buggy pre-1.0 libraries used for critical production softwareNot "critical" as in "if it goes down it's really annoying", but "critical" as in "checks and stores passwords" or "moves money from one bank account to another". simply because it was a wrapper library written in a functional language, as opposed to a more stable library written in an imperative language.<p>I do think if you're using a niche language in an industrial capacity, you need to know how to work with libraries outside the language. Admittedly this is easier for some languages than others. But I've run into candidates who wanted to interview in clojure but who didn't know how to call into pre-provided java libraries.</p>

<p>But we have a lot of sources of information already available that do not seem to be incorporated into any kind of top-level number that we grade ourselves on.<p>- when we have an estimate of how many hundreds of billions it costs to rebuild after a hurricane that would not have happened but for climate change, existing economic processes generate that number<p>- when insurers raise rates throughout a region, this reflects an expectation on the cost of damage, and the change over time reflects the increase in risk we've created<p>- when a heatwave kills a bunch of people, we already have a range of ways of estimating a monetary value for those lives from insurance, healthcare and liability litigation.<p>Further ... suppose your elderly relative left you a bunch of jewelry. You don't know how much it's worth and getting it appraised can actually be a bit complicated and doesn't give you complete certainty over value. But it would be _bonkers_ to continually take unappraised jewelry out into the marketplace, liquidate it, and pretend that the whole sales price was _earnings_. After the transaction, you don't have a thing you had before. You didn't know what it was worth initially but that doesn't mean that it was worthless, and you probably got scammed. Yes, measuring the full environmental impact of all our industries is hard, but pretending it's 0 is silly.</p>

<p>Also this isn't only a gap about environmental issues. 
If you pay X for child daycare and work but only make X+taxes, and have a dumb pointless job, GDP says the economy is at least 2X+tax larger than if you took care of your own child during the day (bc your employer paid you and you paid your daycare).  This seems dumb at an accounting level, even before we consider that you probably get a greater  emotional benefit from being with your child than does the daycare worker.</p>

<p>I don't have any deep background in econ, but do we not need to switch from talking about GDP to talking about a version of Net Domestic Product where "net" includes:<p>- changes to the value of natural and ecosystem resources (e.g. if I clear a forest to sell timber, we must acknowledge some lost value for the forest)<p>- amount of economic transactions in service of mitigating problems created by externalities from other activity (e.g. if my pollution gets into your groundwater, you paying to remediate the pollution isn't "value created")<p>I.e. growth of _actual net value_ still sounds like a good thing to pursue but we let our politicians run around doing anything to maximize GDP without talking about what the "gross" is hiding.</p>
