    "The problem is, I can't think of any evolutionary reason for a new virus to be able get people to be on its side at this level of sophistication. Nor, of course, any normal psychological reason for people to be...

    "The problem with your hypothesis is the growing anti-Asian sentiment among the GOP's base (they created the virus! It's their fault!), and no defense against it by the GOP." True, but it also depends on how it plays out against...
  • Commented on On inappropriate reactions to COVID19
    The discussion on the Republican party imploding is based on 2 simple fallacy: that the GOP can't get minority voters to replace white voters. Also, that Cali is representative of the nation. I'll focus this analysis on Latinos, because there...

    I ran into a question that I thought I'd like to put into the group: Why are Zoom and TickTock starting to rise despite the fact that they have no new technologies compared to their established peers? Perhaps because, just...

    Ok, new tech articles. 1. Alibaba's AI is more accurate than human volunteers in answering questions given just pictures as inputs (81.26% vs 80.83%). https://www.scmp.com/tech/big-tech/article/3145525/alibabas-algorithm-powered-machine-outperforms-humans-understanding a. This has been done for years by feeding the outputs of a Convolutional Neural...

    Unfortunately, the precedent for handling diseases in the West argues against you. Since the 1950s, very few diseases have been eradicated. Most have just been eradicated in the developed world, and still linger in the developing world. That is the...

    "It's also every permutation of the sunk cost fallacy, as people say that they've lived their lives with XXX, and no one' going to take it away from them because YYY." That's true, but deceptive. The best example: look at...

    Let's expand this question: driving vs train vs flying with all of these modes being electric. It seems that electric planes work better for Europe, due to the problem Charlie mentioned. Same with Australia, and likely the US. Not sure...

    I was thinking Berlin Frankfurt, Paris Tolouse/Nice, Madrid Barcelona, Berlin Munich, possibly Rome Catania and Copenhagen Stockholm. Btw, these statistics look at just one leg, and don't consider connecting flights. Also, Lonon Dublin is much higher when you consider city...

    BTW, here were the 20 busiest air routes in Europe in 2016: https://www.telegraph.co.uk/travel/destinations/europe/articles/europe-busiest-air-routes/ Some of them look like it would be beneficial to add faster trains. PS: "Using your metrics, this means that train travel from Beijing to anywhere in...

    You may be correct for Europe, but there's a few reasons that the article chose Beijing-Shanghai as an example. 1. It is the busiest and most profitable high speed rail route in China, if not the world. Despite this, the...

    Here's some news: 1.a. Starlink had a download speed 97.23 Mbps and latency of 45 ms compared to 115.22 Mbps and 14 ms average for the US https://www.businessinsider.com/spacex-starlink-internet-elon-musk-speed-test-broadband-2021-8 b. While the US is worse, in the UK "The proportion of...

    More tech news 1. China is continuing its secret plan to develop its suborbital spaceplane. To me, this reads like an autonomous Virgin Galactic plane. Like the XS-1, it reads like a solution in search of a problem. https://archive.is/D8dtk 2....

    "Re regional dialects. I read - it might have been in Sapir - that before WWI? WWII? there were 236 mutually incomprehensible dialects in the UK. Before WWII, in the US, there were six." The US situation was even more...

    Looks like electric puddle jumpers are getting more capable. https://www.reuters.com/business/sustainable-business/united-airlines-buy-100-19-seat-electric-planes-heart-aerospace-2021-07-13/ In 2018, 74% of business travel within the US was within a range of 250 miles, per the DOT. "Still, at 123 miles, the median one-way distance for business trips...

    In AI and space news, 1. In 2010, China tested a submarine drone that can independently destroy an enemy sub https://www.taiwannews.com.tw/en/news/4244419 2. A Swiss company named Zoundream uses ML to automatically translate the cause of baby cries. The company is...

    I read about In-Space Missions, which launched a satellite on the last SpaceX rideshare. Since the article is paywalled, I included the interesting bit below "Historically, each launched satellite has served a sole purpose. Liddle's team, however, is not only...

    While it's reckless to own an exotic cobra, how many people die from snakebites in the West? The biggest problem with exotic pets is that they inadvertently become invasive species. It's more likely that people will die from exotic pets...
  • Commented on Starship bloopers
    Thanks Charlie. Which configuration would make more sense, hundreds o satellites in GEO or thousands in Starlink's orbit? The reason I'm asking this is that I ran across the following commentary: "With Starship, GEO will become uneconomical. Everything that can...

    https://spacenews.com/chinas-super-heavy-rocket-to-construct-space-based-solar-power-station/ China just announced they're building a space-based solar power system. They'd be using the Long March 9 **Starship clone** to launch it. While I doubt this system is more economic than a terrestrial system, there are a few caveats...

    I was going to wait until the next thread on Bitcoin to bring this up, but what's going on with Bitcoin and Central America is absolutely amazing right now. Short version: Latin American leaders rather liked President Trump. As long...

    Looks like I missed the discussion about whether shrinking populations are good for capitalism or not. My main critique of the discussion is that it focused primarily on goods (the secondary sector). In the EU, Labor Force Participation was 5%...

    "I contend that it is. Without a growing population you won't have colonization. You might have exploratory outposts, but they won't prosper without a (self sustaining) growing population." Would a resort town on the Moon count as an exploratory outpost,...

    I don't think that Manchin is blocking things due to blackmail, and I don't think his arm can be twisted 1. Manchin comes from a VERY red state. Furthermore, this is the state with the coal miner culture. Wyoming produces...

    Since the topic has shifted to Vietnam, I'd like to offer a perspective from one of my former teachers. He was a Vietnam vet. It's been decades, so I don't remember it completely. I'll try to reconstruct it below "In...
