And to power all those fused-multiply-add circuits, Meta will likely soon be involved in the construction or restart or life-extension of nuclear fission reactors, just like Microsoft and Google and Amazon (and Oracle, allegedly).
Quoting Yann LeCun (Vice-President, Chief AI Scientist at Meta):
AI datacenters will be built next to energy production sites that can produce
gigawatt-scale, low-cost, low-emission electricity continuously.
Basically, next to nuclear power plants.
The advantage is that there is no need for expensive and wasteful
long-distance distribution infrastructure.
Note: Yes, solar and wind are nice and all, but they require lots of land
and massive-scale energy storage systems for when there is too little sun
and/or wind. Neither simple nor cheap.
