I disagree, with the projected doubling by 2030 we're looking at 3% of global electricity consumption or 3.4 EJ, less than 1% of final energy consumption.
That is moderate. Energy-intensive industry is around 130 EJ, and global final energy consumption > 450 EJ.
Existing documented applications of today's AI have the potential to decrease energy consumption by >13 EJ/year by 2035.
Now that was about operational energy consumption. Someone might bring up manufacturing and construction.
From what I could find the climate impact of those are estimated somewhere between 10-35% of the total climate impact of data centers, so relatively small compared to the operational energy consumption.
It is very hard to justify more than moderate environmental impact here, in my opinion.
For the benefits of AI, my personal results have been great, so I am quite optimistic. And objectively, I find it hard to ignore recent results in mathematics and security research.
