The current moral panic also means that a really important question is missing from public discourse: what would a world suffused with this technology do to the planet? Which is worrying because its environmental impact will, at best, be significant and, at worst, could be really problematic. How come? Basically, because AI requires staggering amounts of computing power. And since computers require electricity, and the necessary GPUs (graphics processing units) run very hot (and therefore need cooling), the technology consumes electricity at a colossal rate. Which, in turn, means CO2 emissions on a large scale — about which the industry is extraordinarily coy, while simultaneously boasting about using offsets and other wheezes to mime carbon neutrality. The implication is stark: the realisation of the industry’s dream of “AI everywhere” (as Google’s boss once put it) would bring about a world dependent on a technology that is not only flaky but also has a formidable — and growing — environmental footprint. Shouldn’t we be paying more attention to this?
