I'd really like to see a source for the first guy's numbers, especially how he accounts for things like training and water usage at the power plant, and as for the second guy, Anthropic is not preserving shit. The Internet Archive preserves books. Anthropic scans them and doesn't publish the scans so that they can train an LLM that might or might not be able to regurgitate some fragments of that text, and publish that. That's preservation in the same way that painting a picture of you is keeping you alive forever.

Also, neither of those address the effects on creatives' livelihoods or the mental health of LLM users. Chatbot psychosis is real. People who routinely use LLMs to do things provably become worse at doing them without them. Students use LLMs to make an end run around having to learn everything they need to know to be effective members of a society, like how to articulate their points, how not to fall for rhetorical traps, what history was really like, and between that and the disastrous effects of No Child Left Behind, teachers are quitting in droves and there's a literacy crisis.
