Jevon's paradox is not inevitable, and only happens in a very few situations, and certainly not all.
And your statement of it is incorrect. It can result in greater demand, but it's not about resulting greater resource usage.
Some minority of efficiency improvements can sometimes lead to greater resource consumption, but overall efficiency does result in less resource usage.
It calls into question the byline "which could mean lower energy demands."
Ie: more efficient steam engines lead to both an increase of steam engine throughput as well as coal consumption, an increase in AI efficiency can lead to an increase in training throughput and energy consumption.
The paradox is a result of prevalence scaling faster than efficiency and efficiency driving prevalence.
