I saw a tweet that started with “BREAKING:”, what more do you need?

I am not voting for anyone in the 2028 primary who does not agree that the US should comply with International Criminal Court arrest warrants. If the subject is no longer in government, they need to be dragged onto a plane and sent to stand trial.

The graphs in the paper show the temperature 1 km away from the data center being 8°C higher and attribute that to heat emitted by the data center. That should start the alarm bells that something isn't right with this paper.

Here's a post going into the problems with it;

I’ve purchased generic medications on DNMs before. There was a user “Indiapilldaddy” who sold hundreds of different generics. Antibiotics, antivirals, cholesterol, blood pressure, etc. With the review system on the DNMs it’s probably more trustworthy than some random website that pops up.

“Like a 12 year old boy after watching his first episode of Baywatch, the US is clumsily fiddling with its negotiations.”

Natural gas is used to produce hydrogen, which is then used in the Haber-Bosch process to produce ammonia from nitrogen in the atmosphere. Only about 6% of natural gas is used to produce hydrogen, so even if the price were to rise substantially, we could divert natural gas from other uses and have plenty for making ammonia. We also have other ways of producing hydrogen, it's just that natural gas is more established.

PEM electrolyzers paired with cheap solar in countries with high insolation can now produce hydrogen for less than the cost of natural gas, but we're only recently starting to see the construction of the large-scale green ammonia plants needed to accomplish this. Egypt is currently constructing a 100-MW green ammonia plant powered by solar energy. Even if you didn't have enough PEM eletrolyzers you could still just pass current through some salt water and produce hydrogen, albeit much less efficiently.

It's not going to be a catastrophic issue.

Is there more detail on the process beyond what’s in the blog post? I could see a scenario in which the training data was just generated by running multiple playthroughs on a $500,000 GPU at impossible quality, creating a copy of what that would look like on a mid-range GPU, and then training a model. I’m not sure I would object to that.
