> Compare that to ~30% of all energy use for transportation

Transportation, especially ALL transportation, does a LOT. You're looking for ROI not the absolute values. I think it's undeniable that the positive economic effect of every car, truck, train, and plane is unfathomably huge. That's trains moving minerals, planes moving people, trucks transporting goods, and hundreds of combinations thereof, all interconnected. Literally no economic activity would happen without transportation, including the transition to green energy sources, of which would improve the emissions from transportation.

I think it might be more emissions-efficient at generating value than AI by a factor exceeding the 7.5x energy use. Moving rocks from (place with rocks) to (place that needs rocks) continues to be just an insanely good thing for humanity.

Also, I'm not sure about your math. 4% would be 4% of the whole like in a pie chart, not 4% of the remainder after removing one slice. 4% AI, 30% transportation, 66% other. I don't know where that 40% is from.

40% is for energy use in the US in the form of electricity. It was a rough number that I pulled from my memory. It is roughly right though. Check https://www.eia.gov/energyexplained/us-energy-facts/

AI is not currently 4% of the energy market of the US. Only the grid. I should have been more clear about the ALL ENERGY vs GRID distinction.

I really made no statement on the value of doing things. Transportation is obviously very valuable. I just wanted a more fact based conversation.
