fact of the matter is that if AIs externalities were exposed - that is massive energy consumption - to end users and humanity in general, no one would use it.
I think this is wildly optimistic about how environmentally conscious customers of LLMs are. People use fossil fuels directly and through electricity consumption in a unconscionable way at a scale wildly exceeding what a ChatGPT user's energy expenditure is.
We desperately need to rapidly regulately down fossils usage and production for both electricity generation and transport. The rest of the world needs to follow the example of the EU CO2 emissions policy which guarantees it's progressing at a downwards slope independent of what the CO2 emissions are spent on.
