On one hand, there is reason not to panic. Making that sort of switch would require more than 4 million powerful computer chips known as graphics processing units (GPUs). These are currently in huge demand, with limited supply, and would cost S100 billion, which even Google’s deep pockets would struggle to fund.

On the other hand, Als energy consumption will present a genuine problem in time. Nvidia, which sells 95 per cent of the GPUs used for Al, will ship 100,000 of its A100 servers this year, which can collectively consume5.7 terawatt-hours a year.
