Unpopular opinion: it’s not enough for a statement to sound like it could be true, or for a statement to try to goad people on the “right side” into doing the “right thing,” if that statement isn’t actually true

What's weirding me out is that in this graph that's circulating it look like folks somehow manage to build data centres and get them fully operational in less than a month. At zero months and before, practically nothing; at just one month, absolutely everything. Is that explained in the paper?

Graph from the hot datacentres paper showing normalised temperature increase on the y axis and time from AI data centre in months on the x axis. The red line indicating the relationship between the two rises a tiny little bit from minus ten months to zero months and jumps massively thereafter to a higher constantish level.
