  • electric cars release more CO2e than fossil-fuel cars

    India’s grid was about 37% renewable in 2020. I’m seeing estimates of 46% renewable as of now, but those aren’t official. So that conclusion is very unlikely. What is possible is that EV subsidies might be encouraging people to buy electric cars instead of petrol bikes, which could increase emissions.

    If this is true, would it also be true for coal-to-electricity trains vs more straight fossil-fueled trains?

    No, because diesel locomotives are actually diesel-electric - the diesel power is used to generate electricity, which then turns the wheels. So electric locos are simply replacing the very heavy, noisy and dirty diesel engine with a stationary power plant that can be located somewhere remote, much more efficient and does not need to be dragged along with the train. (They are also faster and more powerful, which is probably the bigger reason for electrification.)








  • I think it would be more correct to say that quality control in Chinese science is very poor. I have seen top quality research, and I have also seen crap that should not have been published at all. But the sheer quantity of output means that the next big discovery in <insert field> will be from China.

    OSTP is focused on removing regulations to science and tech bc they argue they are slowing us down in the AI race against China.

    I don’t work on AI, but in my field I have seen the insane speed and scale of Chinese research. Now I’m from a developing country; the US can probably give better funding than we can, but I am inclined to agree that Chinese science does benefit from easier and better funding and a faster administrative process.

    AI data in China is very poor likely bc of the lack of regulations

    The big problem for AI research in China seems to be a shortage of high-end GPUs due to the trade wars. China is very strong in maths and comp sci, and they are finding workarounds, but it is still a pretty hard barrier.


  • Amazon/Bezos is probably getting some sweet federal kick backs

    I think it’s more a threat against employees. The robots can be used as scabs.

    which, until Jan. 2025, was one area that the U.S. had unquestionably dominated China

    China had more scientists and papers well before this year. And China dominates particularly in fields like maths, computer science and manufacturing.

    they are indeed going to try to replace scientists with robots

    I can actually think of a lot of uses for robots in research. And, of course, there are a lot of robots in labs already; they just don’t look like humans.











  • Corruption. The Awami League was the party that led Bangladesh to Independence. Recently, they tried to offer some number of government jobs to veterans of the independence struggle. This was seen as nepotism (since most such veterans would be members of the Awami League, or their friends / relatives). The initial student protests were then taken over by, depending on who you ask, religious fundamentalists, Pakistan or the CIA. The current govt is seen as a US puppet, while the BNP are seen as pro-Pakistan.
