There has been a lot of talk recently about building AI data centers. Massive data centers. Recall that famous one posted by Zuck superimposed over Manhattan. The thought of these monstrosities sucking up water and power for the sake of ChatGPT tokens gets some people very worried. What if we can put all of that in a shoebox? That’s the pitch from a young deeptech startup called Snowcap Compute, which I met with during my recent visit to the US. They’ve been working on something that promises miniscule heat dissipation and speeds in the hundreds of gigahertz. And it depends on superconductors. It sounds like sci-fi but the technology has a heritage stretching back to IBM in the 1960s. I must admit that this one is rather heavy. But I can’t stop thinking about it.
