AI data centers have a power problem nobody likes to talk about. A single rack of computers can now use more electricity than an entire office building.

One new chip, which looks more like a piece of plywood than a processor, delivers similar performance on a fraction of the power. Tech investing veteran George Gilder says that efficiency gap could decide who wins the next stage of AI.

Gilder has identified three companies positioned around this power breakthrough, calling them the Trillion Dollar Triangle.
