<p>It's quite fitting that the topic of this thread is self-correction. Self-correction is a trivial existence proof that refutes what LeCun is saying, because all the LLM has to say is "I made a mistake, let me start again".</p>

<p>Mostly terrorists are dead and this killed far less civilians than the alternative ways of waging war (ground invasion or bombing campaign). This is the level of surgical operation that everyone was calling for since Hezbollah declared war on Israel on October 8th, and now that Israel is delivering that level of precision there's still some people complaining, it's unbelievable how naive some people are.</p>

<p>It's good we have different states/schools trying different things, all within the realm of sensible ideas. This creates natural experiments which will be studied in detail, and which will guide evidence-based policymaking.<p>There's enough plausible evidence linking social media to problems in youth that we have to bite the bullet and try something, then reassess afterwards, rather than be caught in analysis paralysis about what may go wrong with attempts to fix the issues.</p>

<p>They relied on the taxpayer to fund their de facto customer service. It's like aged care homes overusing a public ambulance service instead of hiring an on-call doctor or nurse. Or shops not hiring security and overusing police resources.<p>Public services are there to be used, but there's a line that gets regularly crossed by profit-seeking entities who do not optimize for public good and see public resources as something to be used up as much as possible as long as they can save a dollar.</p>

<p>Open sourcing benefits everyone equally. Given that the US is currently ahead, it's helping China to make gains relative to the US that would have been very difficult otherwise. It's leaking what should be state secrets without even needing the CCP to do the hard work of espionage.</p>

<p>If it was liberal minded people like Deng as leader of China and Gorbachev as leader of Russia I would care a lot less and may even be in favor of open source despite their autocratic system. They'd be trending towards another Singapore at that point. Although I'd still be uneasy about it.<p>But I'm looking at the present moment and see too many similarities with the fascist dictatorships of the past. The nationalism, militarism, unreasonable border disputes and territorial claims and irredentist attitudes. The US just isn't <i>that</i>, despite their history.</p>

<p>US has to win the race because while it's true that it's no angel, it isn't an authoritarian dictatorship and there isn't an equivalence in how bad the world will end up for you and me if the authoritarian side wins the race. Monopoly power will get abused the most by the least democratic actors, which is China. We need multiple actors within the US to win to balance power. We don't need or want China to be one of the winners. There is no upside for humanity in that outcome.<p>The US policymakers have figured this out with their chip export ban. Techies on the other hand, probably more than half the people here, are so naive and clueless about the reality of the moment we are in, that they support open sourcing this tech, the opposite of what we need to be doing to secure our future prosperity and freedom. Open source almost anything, just not this. It gives too much future power to authoritarians. That risk overwhelms the smaller risks that open sourcing is supposed to alleviate.</p>

<p>China can not win this race and I hate that this comment is going to be controversial among the circle of people that need to understand this the most. It is damn frightening that an authoritarian country is so close to number one in the race to the most powerful technology humanity has invented, and I resent people who push for open source AI for this reason alone. I don't want to live in a world where the first superintelligence is controlled by an entity that is threatened by the very idea of democracy.</p>

<p>This is not a trivial point. Selective pressures will push AI towards unsafe directions due to arms race dynamics between companies and between nations. The only way, other than global regulation, would be to be so far ahead that you can afford to be safe without threatening your own existence.</p>

<p><p><pre><code>  "French electricity prices turned negative as a drop in demand and surging renewables output prompted some nuclear reactors to power down."
</code></pre>
This is an issue with nuclear in a net zero scenario. Nuclear starts out at 90%+ capacity factor, like in California today. But as fossil fuels become a low percentage of the grid, you inevitably get a low capacity factor which increases LCOE. Even if you don't want any renewables and you only build nuclear, the problem is demand isn't static so you have to overbuild nuclear by a lot and run at a low capacity factor, or you build storage, either of these increases LCOE.<p>The sensible thing will be to use renewables on top of nuclear rather than overbuild nuclear, like what France is doing. But that will also eat into capacity factor when it's more windy and sunny like what France experiences.<p>Just something to keep in mind when you hear people talk about nuclear costs. Multiply it by at least 1/0.7 if they haven't taken this into account.</p>

<p>Similar. Retail panels can go as low as $0.2/W for the end consumer, so assume that manufacturing costs are $0.1-0.16/W for standard solar panels.<p>But these are translucent. They'll be put onto windows. So even if they're 50% more expensive, it's serving an adjacent use-case.<p>The more interesting figure is they're getting 160W/m^2. That's very large, and it'll be a big deal considering there is more vertical surface area than rooftop area on buildings. Standard solar panels get about 220W/m^2.</p>

<p>Reminds me of the AlphaCode approach.<p>Why do you say it's sampling programs from "training data"? With that choice of words, you're rhetorically assuming the conclusion.<p>If he only sampled 20 programs, instead of 8000, will we still say the programs came from "training data", or will we say it's genuine OOD generalization? At what point do we attribute the intelligence to the LLM itself instead of the outer loop?<p>This isn't meant to be facetious. Because clearly, if the N programs sampled is very large, it's easy to get the right solution with little intelligence by relying on luck. But as N gets small the LLM has to be intelligent and capable of OOD generalization, assuming the benchmark is good.</p>

<p>Winter being a problem really depends on location. Seasonal variability is much lower near the equator. Also batteries are becoming a solved tech. Also wind is anti correlated with solar, it's stronger in winter and at night. So you want 50-50 to minimize the need for storage.</p>
