Things are already much better than they used to be. The 2003 heatwave killed ~70k. This year's heatwave was worse, but the number of deaths probably didn't go much beyond 20k.

I've spent more time in the Andes than in Lima. The Quechua are clearly an indigenous group, but they have been forced to adopt most of the European cultural package. If you travel in Russia, you can find many ethnic groups in similar situations.

Ignore the political aspects for now and focus on culture. And feel free to use "Roman" if "European" sounds wrong. But "Western" is wrong, because the same cultural sphere extends to Australia, New Zealand, and Russian Far East.

From my perspective, as someone from the Northern fringes of Europe, Latin American society and culture feel fundamentally familiar, while Middle East and North Africa don't. Out of the Latin American countries I'm most familiar with, Peru feels more European and Chile more American. Peru feels more like an Old World country, while Chile used to be a sparsely populated frontier.

Europeans definitely don't view other Europeans as kin. They are foreigners with a lot of shared history and culture. Both World Wars were fought because Europeans saw other Europeans as fundamentally different.

All real negotiations are private. When politicians debate or negotiate in public, they inevitably start talking past each other to the general public.

Voting rituals would be a waste of time. The confirmation vote is not just about the President of the Commission but the entire package, including other major positions in the Commission and major policy directions. If no party has a majority, no candidate can hope to get majority support before the whole package has been agreed on.

That's how multi-party parliamentarism usually works. A minority is not allowed to choose the leader just because they are a slightly larger minority than the others.

Because no party has an outright majority, there are weeks of negotiations after the elections, as the parties try to find a compromise acceptable to a majority. Once a deal has been reached, the parliament votes to confirm it. If the vote fails, the parties return to negotiations.

Von der Leyen was chosen to head the Commission, because she was an acceptable compromise. All lead candidates had been tried before her, but all of them failed to obtain majority support in the negotiations.

> Culturally, America is much closer now to Latin America or Asia.

That's an interesting statement. From my perspective, Latin America is clearly European, in the sense I understand the concept. It feels much like Russia. Major cities and densely populated regions are European, with local characteristics. But there are other cultures around, and they are dominant in some regions. And if you travel in fringe areas, you often find peoples that have not fully accepted the European cultural package.

I don't see Europeanness as something associated with specific ethnic groups or states. It's a cultural package that started spreading from the Roman Empire and was imposed upon different peoples at different times. Where I'm from, that happened ~800 years ago, though rural areas often kept to the old pagan ways until the 17th century. That time frame is not too different from what happened in the Americas.

> At least 25% of us Americans have never had blood or ethnic ties with Europe.

> African Americans make up around 15% of the US, Asian Americans around 7%, Arab Americans around 1.5%, and Native Americans around 2%.

Those are cultural identities. The average African American has ~20% European ancestry. Latin Americans vary by country and region of origin, but on the average, they have more European than Native American ancestry.

Payloads are expensive, because high-value businesses can outbid low-value ones. By the time there is enough launch capacity for low-value businesses, manufacturing improvements should have made launch vehicles even cheaper.

Or you could look at this from another perspective. The services enabled by infrastructure must be more valuable than the infrastructure itself to justify the investment.

In that scenario, most of the value would be in Starlink.

Launch vehicles have always been the cheap part in going to space. Payloads tend to be more expensive, and the actual value is in the services enabled by the payloads.

You have a few misconceptions.

The actual expectation is that after finishing PhD, you take a journeyman position, where you can practice the skills needed in an academic career and gradually gain independence while being mentored by a senior academic. Then, if you were successful, you get a permanent position. The postdoc path fails, as there is no clear path to a permanent position. The assistant professor path fails, because the funding system requires you to become a manager without sufficient experience.

European PhDs vary in duration. The most common system is 3+2+4 years for bachelor's + master's + PhD, which is not that different from the American 4+5 years for bachelor's + PhD. (Those are nominal durations, and actual studies usually take longer.)

In most European countries, a postdoc is a nice enough middle-class job. If you are interested in an academic career after finishing PhD, you have good chances of getting a postdoc position. The real bottleneck comes after the postdoc stage, as faculty positions are scarce in most European universities.

The US spends less on academic research than the OECD average. See, for example, https://ncses.nsf.gov/pubs/nsb202326/academic-r-d-internatio...

From a European perspective, the most noticeable sign of this is the scarcity of postdocs at American universities. Some fields and individual labs are better funded, but on the average, the universities lean heavily on students doing the actual research.

Because there is less competition for jobs and grants. Europe spends more on academic research (as a fraction of GDP) than the US, but there are more people competing for the funding.

And the foundations of those statistical approaches are built on heuristics and shortcuts.

For example, sequencing instruments include base quality strings in the output. Base qualities are estimates how likely the instrument got each sequenced base right. But most people don't want to store that much noise, especially when the actual data is highly compressible. So the base qualities get quantized using more or less principled methods that seem to work well empirically.

Read aligners make similar estimates of how likely they got the correct alignment for each read. Those estimates are typically based on simplistic models and a number of assumptions. There are two main components in the estimate. One is based on comparing the primary alignment the aligner chose to the secondary alignments it also found. Another is an estimate that the aligner didn't find the correct alignment, because that part of the sequenced genome is too different from the reference. The latter is obviously handwavy. And the aligner cheats in the former. Because people don't want to wait 10x or 100x longer for better results, the aligner gives up early and estimates how good secondary alignments it might have found if it had actually done the work.

And then there is variant calling. At some point, the state-of-the-art callers were statistical. But then people got better results with neural networks. Or at least the results were empirically better.

I guess you had more of those people after the revolution.

Many combat veterans react to anything resembling gunfire and explosions. And you can add drone noise to that these days.

The strategic level is the level that matters.

In a video game, military forces fight other military forces and the stronger side wins. In the real world, a military force may choose to fight enemy forces, if it believes that's the best way to advance its goals. But if the enemy is clearly stronger, fighting it directly is probably counterproductive, and it may be more useful to hit softer targets instead.

US forces suffered limited casualties, but that wasn't particularly relevant. Iran realized quickly enough that engaging US forces directly wasn't an efficient way to use its resources. It targeted infrastructure such as oil refineries in Gulf States allied with the US and caused serious enough damage to steer the course of the war.

I think the war revealed two deficiencies in US forces. First, the US did not have sufficient offensive capabilities to prevent Iranian counterattacks. Iranian drones and missiles were cheap and plentiful, while the US used expensive platforms designed for hitting high-value targets. And second, the forces available to defend allied civilian infrastructure were insufficient. The US only had limited forces in the region, and force composition focused heavily on offense.

That's video game thinking. The effectiveness of a military force is not based on its ability to fight enemy forces, but on its ability to achieve its goals and prevent the enemy from achieving theirs.

US military could strike enemy targets and defend itself in the Iran war, just like in other wars in the past decades. But this time, its ability to defend its bases and the countries hosting those bases was clearly insufficient. Due to this deficiency, Iran managed to achieve not only its primary goal (to survive) but also a secondary goal (to make other countries in the region question whether US military presence is an asset or a liability).

Cheap drones and missiles create an asymmetry between offense and defense. A small offensive force can strike anywhere it wants, but the other side needs sufficient defenses at every target worth striking. The US had sufficient offensive forces, but it lacked the several times larger defensive forces needed to protect the region from Iranian counterattacks. Its regional allies might have had those, if the US had told them in advance and given them time to mobilize.

Public goods can be contracted out to private entities. And this can be done independently in each region, without having a single central contractor.

EU countries privatized their postal services decades ago, because governments are not allowed to compete with private entities in the market (unless explicitly allowed by EU-wide laws). And because the idea felt good, the same privatization extended to territories outside the EU, such as Greenland.

You often do, if the street has been there for a while. The exact location of underground infrastructure was rarely documented in the past. While the city should have a general idea of what lies under the street, you usually have to dig the street up to determine where you can install new infrastructure safely.

That would be a trap. It's healthier for a non-profit to have many small funders than a few large ones.

Larger cities would help more, as the root issues are education and specialization.

A city should be large enough to have multiple potential employers to minimize the risk of getting trapped in a bad job. If you are single, a smaller city can be viable if there is a concentration of businesses in your field. But that won't work for an educated couple, if they are in different fields.
