Its ravenous need for computational power has overwhelmed chip manufacturers and power companies alike.
While our current AI obsession is likely a bubble ready to burst, we won't simply stop using computers. Since their first invention, computers have continued to grow more powerful, and our civilization has grown ever more dependent on them. Computation defines our civilization.
Perhaps computational power is what defines any advanced civilization. If that's the case, then the most advanced civilizations in the universe would push computing to its most powerful and efficient state. That's the idea behind a new paper on the arXiv preprint server.
In it, the author argues that hyper-efficient computers would be central to any alien civilization. The author further argues that this would give their star systems a distinct signature, which he calls a Slysh halo. The term is named after V.
Slysh, who first argued that advanced civilization is best served cold. If you can get your technology to operate at supercool temperatures, then it will likely be more efficient. Computers are a good example of this.
All non-reversible computations generate waste heat. Thanks to the laws of thermodynamics, this means there is a level of inefficiency to these computations. Our current computer data centers generate so much heat they need cooling systems to keep from melting.
