And they are expensive to run because they require huge amounts of electricity. More, in fact, than we currently have, which is why electrical bills are spiking here and there around the world. Why does this matter? Because when the 19th-century railway bubble burst, we were left with railways. When the early-electrification bubble burst, we were left with the grid. And when the dot-com bubble burst, we were left with a lot of valuable infrastructure whose cost was sunk, in particular dark fibre. The AI bubble? Not so much; What with GPU burnout and power charges, the infrastructure is going to be expensive to keep running, not something that new classes of application can pick up and use on the cheap. Which suggests that the post-bubble hangover will have few bright spots.
