Yes, and consider that with the current hype around AI and enough (venture) capital there will be several corporations competing for the best AI and suddenly we are at several "nuclear plants" or equivalent energy "consumption".
I don't see increasing demand for nuclear power as a disadvantage. We have nuclear material that can last humanity 1000s of years at least. The CO2 footprint is an issue but nuclear is much better than others. Personally, I think it's better we utilize more energy and discover new breakthroughs while society is relatively stable and functioning, because there's no guarantee that it will last. Population collapse seems imminent in more educated societies, even China and India are trending this way now. Without some level of AI assistance, humanity would likely lose a great deal of productive output.
Also, if this path to AGI does not work out, its not as though the nuclear reactors will be wasted. People will find something else to do with the energy.
Sure I agree, but if we compared value it generates per unit energy it would still probably be better than many non-essential industries: the entertainment industry, fashion industry, alcohol, etc. Even in the current state LLMs can provide more useful practical value compared to industries with higher energy and CO2 footprints.
