> Though I'm not sure we should be killing the earth for better search

Are we, though? What I have read so far suggests the carbon footprint of training models like gpt4 was "a couple weeks of flights from SFO to NYC" https://andymasley.substack.com/p/individual-ai-use-is-not-b...

They also seem to be coming down in power usage substantially, at least for inference. There's pretty good models that can run on laptops now, and I still very much think we're in the model T phase of this technology so I expect further efficiency refinements. It also seems like they have recently hit a "cap" on the increase in intelligence models are getting for more raw power.

The trendline right now makes me wonder if we'll be talking about "dark datacenters" in the future the same way we talked about dark fiber after the dot com bubble.
