• The data center backlash is a product of two mutually reinforcing dynamics: 1) Locally, it's material concerns (noise, water, electricity) and process failure (NDAs, tax subsidies) 2) Nationally, it's broad anti-corporate and anti-AI sentiment (AI companies are screwing you over to get rich off dumb toys) Social media + political campaigns amplify hyperlocal grievances into a broad populist movement, and there's no compelling "pro data center faction" to make the opposite case

In general, when we are generating tokens, there can be multiple high-scoring tokens at certain next-word positions. Usually, we sample with top-k or top-p sampling so the highest-scoring token is most often selected (if we repeat the sampling many times), but other tokens may be selected as well. With watermarking, there is a key that says which of the (ideally equally) highest-scoring tokens to select. Or, more concretely, the secret key and previous token influence the…
