Their capacity for flight is magical, almost animate, reflected in the names by which they are known around the world. In Greek, they are χαρταετοί, paper eagles, and the Germans call them Drachen, dragons. French children float flying stags (cerf-volant) above the earth — although “cerf”, here, is likely a corruption of the Occitan serp, snake — and in Russian, too, they are serpents of the ...

AI platforms are subsidizing their products to generate massive demand, but this strategy is unsustainable as costs are rising and users are being forced to switch to token-based pricing, which is eye-wateringly expensive. The AI industry is facing a debt crisis, with estimated debt of $3T, and needs to replace human labor on a colossal scale to service the debt, which is a daunting task.

The deadly rise of giant trucks and SUVs
