It’s weird that water became THE issue for why many people (publicly) dislike AI. Of all the concerns about AI use, even just limiting it to environmental concerns, water use is generally one of the least important.
But when I speak with people, especially younger ones, water usually comes up first

Finally came around to reading @samwho.dev's article about prompt caching which - turns out - is only around 10% about prompt caching because in order to understand it you need a good idea on how LLMs work 😆
As per usual Sam nailed it 👏🏻👏🏻

The kids are alright.
I'm not sure *how* it happened, but I encounter a lot of undergrads proposing remarkably thoughtful and well-informed indep. study distant-reading projects. It's not like those methods got incorporated in the curriculum! But students are somehow self-educating—possibly with LLM assistance?

Fwiw I think this is actually backwards. My experience with LLMs has been that they are actually*incredibly* good at precisely this thing, and that this may in fact be one of their most beneficial aspects.
Not a historian but like to research. The AI might summarize what I'm looking for, but it doesn't find what I'm *not* looking for. The book on the shelf next to the one I wanted. The insight in chapter 6 based on the quote I needed from chapter 4.

The fun thing about the AI as dotcom crash metaphor is that it's bullish for AI. While companies like Webvan, Kozmo & Pets. com failed - today we have Amazon, DoorDash & Chewy.
We also have Netflix, TikTok, Uber and lots of other companies we couldn’t have imagined in 2001.
AI will be similar.

Remember the dotcom bubble and what happened to the internet after that? The AI bubble may well pop in 2026 but if you expect that it will bring the end of AI you’re gonna be sorely disappointed.

To be sure there’s real debate about whether GenAI is worth the cost (in the academic lit see Humlum and Vestergaard 2025), but it’s quite sad that more people don’t have the same doubts regarding cattle “farming.”
speculative promises about what AI could maybe possibly be used for don't match up with reality, and drawing contrasts to how much water humans take to live, or to raise cattle, or to manufacture a t-shirt, are all wildly different from the question of AI facilities and their eminent impacts

endlessly interesting to me that people think this first claim is true. why? I tend to think it’s mostly because RLHF’ed outputs with weak prompting are generic
AI will only go down the paths most traveled, which is what lawyers pressing courts toward new ways of seeing must transcend. AND the only way to diverge from the old paths is to become intimately familiar with them - to gather the source materials with which the brain does its unique alchemy.
