Also as noted in the prior dupe, the article also misunderstands it's own topic, as explained in (https://en.wikipedia.org/wiki/Jevons_paradox):

In economics, the Jevons paradox occurs when technological advancements make a resource more efficient *to use*; however, as the cost of *using the resource drops*, if demand is highly price elastic [PED], this results in overall demand [for the resource] increasing.

The cost to use tokens is already zero or deeply negative, depending on your accounting. And the author is mistaking the cost of 'creating/extracting the resource' (token generation economics) with cost of 'using the resource' (calling an API). I don't think we'll understand the true cost of, and demand for AI services for quite some time.
