<p>> <i>For intelligence activities, any handling of private information will comply with the Fourth Amendment, the National Security Act of 1947 and the Foreign Intelligence and Surveillance Act of 1978, Executive Order 12333, and applicable DoD directives requiring a defined foreign intelligence purpose. The AI System shall not be used for unconstrained monitoring of U.S. persons’ private information as consistent with these authorities. The system shall also not be used for domestic law-enforcement activities except as permitted by the Posse Comitatus Act and other applicable law.</i><p>My reading of this is that OpenAI's contract with the Pentagon only prohibits mass surveillance of US citizens <i>to the extent that that surveillance is already prohibited by law</i>. For example, I believe this implies that the DoW can procure data on US citizens <i>en masse</i> from private companies - including, e.g., granular location and financial transaction data - and apply OpenAI's tools to that data to surveil and otherwise target US citizens at scale. As I understand it, this was <i>not</i> the case with Anthropic's contract.<p>If I'm right, this is abhorrent. However, I've already jumped to a lot of incorrect conclusions in the last few days, so I'm doing my best to withhold judgment for now, and holding out hope for a plausible competing explanation.<p>(Disclosure, I'm a former OpenAI employee and current shareholder.)</p>

<p>(Disclosure, I'm a former OpenAI employee and current shareholder.)<p>I have two qualms with this deal.<p>First, Sam's tweet [0] reads as if this deal does <i>not</i> disallow autonomous weapons, but rather requires "human responsibility" for them. I don't think this is much of an assurance at all - obviously at some level a human must be responsible, but this is vague enough that I worry the responsible human could be very far out of the loop.<p>Second, Jeremy Lewin's tweet [1] indicates that the definitions of these guardrails are now maintained by DoW, not OpenAI. I'm currently unclear on those definitions and the process for changing them. But I worry that e.g. "mass surveillance" may be defined too narrowly for that limitation to be compatible with democratic values, or that DoW could unilaterally make it that narrow in the future. Evidently Anthropic insisted on defining these limits itself, and that was a sticking point.<p>Of course, it's possible that OpenAI leadership thoughtfully considered both of these points and that there are reasonable explanations for each of them. That's not clear from anything I've seen so far, but things are moving quickly so that may change in the coming days.<p>[0] <a href="https://x.com/sama/status/2027578652477821175" rel="nofollow">https://x.com/sama/status/2027578652477821175</a><p>[1] <a href="https://x.com/UnderSecretaryF/status/2027594072811098230" rel="nofollow">https://x.com/UnderSecretaryF/status/2027594072811098230</a></p>

<p>It's true that a volatile environment in general is good for certain types of investment banking business, including facilitating this trade. I nevertheless think it's unlikely - honestly, a galaxy brain take - that Cantor Fitzgerald or other investment banks with influence in the Trump administration would push for policies like unconstitutional tariffs just to drive trading revenue. Maybe the strongest reason is that other, frankly more lucrative investment banking activities, like fundraising and M&A, benefit from a growing economy and a stable economic and regulatory environment.</p>

<p>Fixed the “majority” claim.<p>I think a competent opposition party would be great for the US. But regardless of the candidate, US voters had three clear choices in the 2024 Presidential election: (1) I support what Trump is going to do, (2) I am fine with what Trump is going to do (abstain/third-party), (3) Kamala Harris. I think it’s extremely clear 3 was the best choice, but it was the least popular of the three.</p>

<p>I wouldn’t put anything past them, but my impression is that they were just acting as a middleman for this transaction and taking a fee, rather than making a directional bet one way or another. Hedge funds have certainly been buying a lot of tariff claims, giving businesses guaranteed money upfront and betting on this outcome. But for an investment bank like Cantor Fitzgerald that would be atypical.</p>

<p>I don’t see how constitutional changes would help. The constitution already creates separation of powers, limits on executive authority, and procedures for removing an unfit president or one who commits serious crimes. But these only matter to the extent that majorities of elected and appointed officials care, and today’s ruling notwithstanding, there’s no political will to enforce any of them. The plurality of American voters in 2024 asked for this, and unfortunately we are all now getting what they asked for and deserve.</p>

<p>I don't follow.<p>The fertility rate has decreased significantly for US-born women of every race and ethnicity since the 1990s. I couldn't quickly find good stats on trend in birth control usage or labor force participation by race, ethnicity, or immigration status, but I'm skeptical that the trend is in the opposite direction for any particular demographic.<p>So I expect the claims in my previous comment still hold even for, e.g., native-born whites as a subgroup: flat-to-decreasing birth control usage, declining labor force participation, but still declining fertility rate. Obviously the magnitudes of those changes may be different at the subgroup level, but I don't see how the data is compatible with the claims of the comment I initially replied to.</p>

<p>This is surely part of the story historically, but not recently. Women’s labor force participation rate peaked in the late 90s in the US, while total fertility rate is down ~20% since then. <a href="https://fred.stlouisfed.org/series/LNS11300002" rel="nofollow">https://fred.stlouisfed.org/series/LNS11300002</a></p>

<p>The timing for those factors doesn’t match the timing of the fertility decline in the US.<p>Birth control usage is slightly down since the mid 90s. Among sexually active women not trying to get pregnant, the rate has been flat since 2002. <a href="https://www.guttmacher.org/fact-sheet/contraceptive-use-united-states" rel="nofollow">https://www.guttmacher.org/fact-sheet/contraceptive-use-unit...</a><p>Women’s labor force participation rate peaked in the late 90s. <a href="https://fred.stlouisfed.org/series/LNS11300002" rel="nofollow">https://fred.stlouisfed.org/series/LNS11300002</a><p>It’s hard to see how a stronger social safety net would <i>decrease</i> birth rates, but that has actually also decreased, e.g. from welfare reforms in 1996.<p>Meanwhile, total fertility is down ~20% over the ~30 year period since then.</p>

<p>I don’t think the evidence either way is strong enough to call that one a myth. There are lots of other differences between the two countries that could offset the impact of Austria’s childcare subsidies.<p>There are plenty of longitudinal studies from various geographies, which I would summarize as “childcare subsidies increase birth rates in some contexts, but the effects are complex and depend on program specifics.” E.g. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2917182/" rel="nofollow">https://pmc.ncbi.nlm.nih.gov/articles/PMC2917182/</a> and <a href="https://clef.uwaterloo.ca/wp-content/uploads/2024/09/CLEF-075-2024.pdf" rel="nofollow">https://clef.uwaterloo.ca/wp-content/uploads/2024/09/CLEF-07...</a></p>

<p>Civ III is still my go-to activity for long flights with no internet - I've yet to find a better way to instantly time-travel forward 12 hours.<p>I haven't tried OpenCiv3, but I'm glad it exists - getting vanilla Civ III running on MacOS is a hassle and still has issues with e.g. audio and cutscenes. I also hope it leads to a way to improve worker automation. Managing your workers well is important, doing it manually is tedious, and the built-in Automate feature is really bad.</p>

<p>No, but if you run a shadow or offline camera-only model in parallel with a camera + LIDAR model, you can (1) measure how much worse the camera-only model is so you can decide when (if ever) it's safe enough to stop installing LIDAR, and (2) look at the specific inputs for which the models diverge and focus on improving the camera-only model in those situations.</p>
